    Generation of a large combinatorial library of the immunoglobulin repertoire in phage lambda (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: A novel bacteriophage lambda vector system was used to express in Escherichia coli a combinatorial library of Fab fragments of the mouse antibody repertoire. The system allows rapid and easy identification of monoclonal Fab fragments in a form suitable for genetic manipulation. It was possible to generate, in 2 weeks, large numbers of monoclonal Fab fragments against a transition state analog hapten. The methods described may supersede present-day hybridoma technology and facilitate the production of catalytic and other antibodies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huse, W D -- Sastry, L -- Iverson, S A -- Kang, A S -- Alting-Mees, M -- Burton, D R -- Benkovic, S J -- Lerner, R A -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1275-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2531466" target="_blank"〉PubMed〈/a〉

    Sequence-specific peptide cleavage catalyzed by an antibody (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-03
    Description: Monoclonal antibodies have been induced that are capable of catalyzing specific hydrolysis of the Gly-Phe bond of peptide substrates at neutral pH with a metal complex cofactor. The antibodies were produced by immunizing with a Co(III) triethylenetetramine (trien)-peptide hapten. These antibodies as a group are capable of binding trien complexes of not only Co(III) but also of numerous other metals. Six peptides were examined as possible substrates with the antibodies and various metal complexes. Two of these peptides were cleaved by several of the antibodies. One antibody was studied in detail, and cleavage was observed for the substrates with the trien complexes of Zn(II), Ga(III), Fe(III), In(III), Cu(II), Ni(II), Lu(III), Mg(II), or Mn(II) as cofactors. A turnover number of 6 x 10(-4) per second was observed for these substrates. These results demonstrate the feasibility of the use of cofactor-assisted catalysis in an antibody binding site to accomplish difficult chemical transformations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iverson, B L -- Lerner, R A -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922606" target="_blank"〉PubMed〈/a〉

    Chemistry of antibody binding to a protein (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-03-06
    Description: The chemistry of antibody recognition was studied by mapping the antigenicity of the protein myohemerythrin with peptide homologs of the protein sequence. The results suggest that the entire protein surface is antigenic, but the probability of there being antibodies to a given site is influenced by local stereochemistry. Although accessible to an antibody binding domain, the least reactive positions cluster in the most tightly packed and least mobile regions and are closely associated with narrow, concave grooves in the molecular surface containing bound water molecules. The most frequently recognized sites form three-dimensional superassemblies characterized by high local mobility, convex surface shape, and often by negative electrostatic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geysen, H M -- Tainer, J A -- Rodda, S J -- Mason, T J -- Alexander, H -- Getzoff, E D -- Lerner, R A -- New York, N.Y. -- Science. 1987 Mar 6;235(4793):1184-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3823878" target="_blank"〉PubMed〈/a〉

    A stereospecific cyclization catalyzed by an antibody (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-08-28
    Description: A monoclonal antibody elicited by a transition-state analog that is representative of an intramolecular six-membered ring cyclization reaction acted as a stereospecific, enzyme-like catalyst for the appropriate substrate. Formation of a single enantiomer of a delta-lactone from the corresponding racemic delta-hydroxyester was accelerated by the antibody by about a factor of 170, which permitted isolation of the lactone in an enantiomeric excess of about 94 percent. This finding demonstrates the feasibility of catalytic-antibody generation for chemical transformations that require stereochemical control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Napper, A D -- Benkovic, S J -- Tramontano, A -- Lerner, R A -- GM 13306/GM/NIGMS NIH HHS/ -- GM 35318/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 28;237(4818):1041-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3616626" target="_blank"〉PubMed〈/a〉

    Induction of an antibody that catalyzes the hydrolysis of an amide bond (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-02
    Description: Catalysis of amide bond hydrolysis is of singular importance in enzymology. An antibody was induced to an analog of a high-energy intermediate anticipated along the reaction coordinate of amide hydrolysis. This antibody is an amidase with high specificity and a large rate enhancement (250,000) relative to the uncatalyzed reaction. This reaction represents the kinetically most difficult hydrolysis reaction yet catalyzed by an antibody.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janda, K D -- Schloeder, D -- Benkovic, S J -- Lerner, R A -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1188-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3413482" target="_blank"〉PubMed〈/a〉

    Catalytic antibodies (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-12-19
    Description: Monoclonal antibodies elicited to haptens that are analogs of the transition state for hydrolysis of carboxylic esters behaved as enzymic catalysts with the appropriate substrates. These substrates are distinguished by the structural congruence of both hydrolysis products with haptenic fragments. The haptens were potent inhibitors of this esterolytic activity, in agreement with their classification as transition state analogs. Mechanisms are proposed to account for the different chemical behavior of these antibodies with two types of ester substrates. The generation of an artificial enzyme through transition state stabilization by antibodies was thus demonstrated. These studies indicate a potentially general approach to catalyst design.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tramontano, A -- Janda, K D -- Lerner, R A -- GM35318/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 19;234(4783):1566-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3787261" target="_blank"〉PubMed〈/a〉

    Mechanisms of antibody binding to a protein (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-03-06
    Description: The mechanisms of antibody binding to a protein were studied by an analysis of specific amino acid residues critical to nine antigenic sites on myohemerythrin. Rabbit antisera to the whole protein were assayed for binding to more than 1500 distinct peptide analogs differing from the protein sequence by single amino acid replacements. The results, combined with information from the three-dimensional crystallographic structure, were used to evaluate probable mechanisms of antibody binding at individual sites. The data from all sites examined indicate that initial binding to solvent-exposed amino acid residues may promote local side-chain displacements and thereby allow the participation of other, previously buried, residues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Getzoff, E D -- Geysen, H M -- Rodda, S J -- Alexander, H -- Tainer, J A -- Lerner, R A -- New York, N.Y. -- Science. 1987 Mar 6;235(4793):1191-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3823879" target="_blank"〉PubMed〈/a〉

    Antibodies to peptides detect new hepatitis B antigen: serological correlation with hepatocellular carcinoma (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-01-25
    Description: The expression of a previously unidentified gene product, encoded by the hepatitis B virus (HBV) genome, has been achieved with a recombinant SV40 expression vector. Antibodies against synthetic peptides representing defined regions of this protein were used to screen cells infected with recombinant virus as well as tissues naturally infected with HBV. A 24,000-dalton protein (p24) was detected in cells infected with recombinant virus and a 28,000-dalton protein (p28) was detected in tissues infected with HBV. The peptides or recombinant-derived protein were used as antigens to screen sera from individuals infected with HBV. Specific antibodies were detected predominantly in sera from patients with hepatocellular carcinoma. The presence of p28 in tissues infected with HBV and the appearance of specific antibodies in infectious sera establish the existence of an additional marker for HBV infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moriarty, A M -- Alexander, H -- Lerner, R A -- Thornton, G B -- New York, N.Y. -- Science. 1985 Jan 25;227(4685):429-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2981434" target="_blank"〉PubMed〈/a〉
