GONADOTROPIC HORMONE ORIGINATING IN INVERTEBRATE AND METHOD OF PRODUCING THE SAME

摘要

[PROBLEMS] To clarify the structure of a gonadotropic hormone of an invertebrate (Asterina pectinifera). [MEANS FOR SOLVING PROBLEMS] This gonadotropic hormone is a peptide being composed of two subunits, having a molecular weight of from 4500 to 4900 and having a structure wherein these two subunits are bonded via an SS-crosslinkage between SH residues in cysteines contained in them.<I/>A peptide having a gonadotropic activity (a gonadotropic hormone) can be obtained by synthesizing these two subunits, mixing them and oxidizing.
