NEW MATERIAL:A compound shown by the formula (X is H-Tyr-Pro-Glu-Ile- Ser-Trp-Thr-Arg-Asn-Gly-, H-Glu-His-Asp-Pro-Ser-Ala-Pro-Gly-Asn-Aly-Tyr-; Y is optionally amidated or esterified carboxyl; n is 3-5). EXAMPLE:H-Tyr-Pro-Glu-Ile-Ser-Trp-Trh-Arg-Asn-Gly-Cys-OH. USE:Useful for growth of species of yeast, improvement of species, etc. A reagent for study of biochemistry and molecular biochemistry. Exhibiting promoting action on formation of bonded tube, having strong yeast hormone action, the peptide is safe to the human body and can be handled readily. PROCESS:Cysteine-containing peptide is dissolved in water-containing DMF, etc. and reacted with a halogenated polyprenyl in the presence of MGO as a catalyst to give a compound shown by the formula. |
