    Structure of human methionine aminopeptidase-2 complexed with fumagillin (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-11-13
    Description: The fungal metabolite fumagillin suppresses the formation of new blood vessels, and a fumagillin analog is currently in clinical trials as an anticancer agent. The molecular target of fumagillin is methionine aminopeptidase-2 (MetAP-2). A 1.8 A resolution crystal structure of free and inhibited human MetAP-2 shows a covalent bond formed between a reactive epoxide of fumagillin and histidine-231 in the active site of MetAP-2. Extensive hydrophobic and water-mediated polar interactions with other parts of fumagillin provide additional affinity. Fumagillin-based drugs inhibit MetAP-2 but not MetAP-1, and the three-dimensional structure also indicates the likely determinants of this specificity. The structural basis for fumagillin's potency and specificity forms the starting point for structure-based drug design.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, S -- Widom, J -- Kemp, C W -- Crews, C M -- Clardy, J -- CA24487/CA/NCI NIH HHS/ -- CA59021/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1998 Nov 13;282(5392):1324-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.

    Structure of the FKBP12-rapamycin complex interacting with the binding domain of human FRAP (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-07-12
    Description: Rapamycin, a potent immunosuppressive agent, binds two proteins: the FK506-binding protein (FKBP12) and the FKBP-rapamycin-associated protein (FRAP). A crystal structure of the ternary complex of human FKBP12, rapamycin, and the FKBP12-rapamycin-binding (FRB) domain of human FRAP at a resolution of 2.7 angstroms revealed the two proteins bound together as a result of the ability of rapamycin to occupy two different hydrophobic binding pockets simultaneously. The structure shows extensive interactions between rapamycin and both proteins, but fewer interactions between the proteins. The structure of the FRB domain of FRAP clarifies both rapamycin-independent and -dependent effects observed for mutants of FRAP and its homologs in the family of proteins related to the ataxia-telangiectasia mutant gene product, and it illustrates how a small cell-permeable molecule can mediate protein dimerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, J -- Chen, J -- Schreiber, S L -- Clardy, J -- CA59021/CA/NCI NIH HHS/ -- GM38625/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jul 12;273(5272):239-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Baker Laboratory, Cornell University, Ithaca, NY 14853-1301, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662507" target="_blank"〉PubMed〈/a〉
