    Genetic analysis of essential oil variants inPerilla frutescens (1995)
    Springer
    Biochemical genetics 33 (1995), S. 341-348 
    Details
    ISSN: 1573-4927
    Keywords: Perilla frutescens ; Labiatae ; chemotypes ; genetic analysis ; essential oils
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A new chemotype (C type) ofPerilla frutescens (Labiatae) that accumulatestrans-citral as a main component of the essential oil in the leaf was crossed with five other chemotypes containing perillaldehyde (PA), elsholtziaketone (EK), perillaketone (PK), perillene (PL), and phenylpropanoid (PP) as their respective major components for comparison of genetic differences. The analyses of F1 and F2 progenies showed thattrans-citral is accumulated when its metabolism is blocked in the simultaneous absence of a dominant geneN, which is involved in the conversion oftrans-citral into naginataketone viacis-citral, and two polymeric genesFr 1 andFr 2 , which are involved in the conversion oftrans-citral into perillene. On the basis of new data obtained from various intercrosses involving the C type as one of the parents, the genotypes of different chemotypes as well as the sites of action of several genes controlling reaction steps in the biosynthesis of monoterpenes inPerilla have been revised.

    Genetic control of geranial formation inPerilla frutescens (1994)
    Springer
    Biochemical genetics 32 (1994), S. 155-159 
    Details
    ISSN: 1573-4927
    Keywords: Perilla frutescens ; chemotype ; geranial ; breeding
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A novel chemotype (C type) having a lemon-like odor segregated out in the F2 progeny of a cross between PK and PL chemotypes ofPerilla frutescens. Chemical analysis of C-type plants revealed that geranial was the major component of essential oils in the leaves. Genetic analysis suggested that geranial is accumulated by individuals homozygous for two pairs of recessive, polymeric genes,fr 1 andfr 2, which are incapable of converting geranial into perillene.

    Solution structure of human growth hormone-releasing factor fragment (1-29) by CD: Characteristic conformational change on phospholipid membrane (1991)
    New York : Wiley-Blackwell
    Biopolymers 31 (1991), S. 869-876 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: The conformations of synthetic human growth hormone-releasing factor fragment (1-29) in the presence and the absence of l, 2-dimyristoyl-sn-glycero-3-phosphorylglycerol liposome as well as in aqueous 2, 2, 2-trifluoroethanol solution were investigated by CD spectroscopy. The secondary structure of the peptide in each solution was analyzed by two methods. Both results show that the peptide has an unordered structure in the aqueous solution. whereas it folds into helical structure in the aqueous alcohol and in the phospholipid solution. In addition, although the peptide exists as almost complete helix in the 50 vol % aqueous alcohol (80-90% helicity), it does not reach full helicity even in the solution containing excess amount of phospholipid liposome (maximum 65-70% helicity). The conformational difference is explained by the characteristic amphipathy of the peptide, i.e., the necessity to twist the separated amphipathic helical parts in the interaction with the phospholipid membrane probably makes the helicity of the peptide decrease.

    α-Helical assembly of biologically active peptides and designed helix bundle protein (1994)
    New York : Wiley-Blackwell
    Biopolymers 34 (1994), S. 481-488 
    Details
    ISSN: 0006-3525

    Topics: Chemistry and Pharmacology
    Notes: The formation of α-helical assembly by complexing biologically active peptides with de novo designed protein is described. The de novo designed protein described here is a cystinelinked 4-helix bundle protein constructed with 80 amino acid residues and forms a hydrophobic core region surrounded by 4 helices in an aqueous solution. The biologically active peptides, such as melittin and human growth hormone releasing factor, contain the sequences that are able to form amphiphilic helices. These peptides alone do not form the α-helix structure in a diluted solution with low ion strength. But on mixing with the designed helix bundle protein, the peptides are strongly bound to the protein with the induction of α-helical structure in the biologically active peptides. The content of induced α-helix is in accord with that estimated from the amphiphilic sequence. The results mean that a novel architecture composed of α-helices is formed. Fluorescent and temperature-scanning measurement revealed that the α-helical assembly is constructed with hydrophobic interaction. Also, it is shown by means of fluorescence depolarization that the assembly has a compact globular form corresponding to 1 : 1 complex. © 1994 John Wiley & Sons, Inc.
