Abstract
P. chrysogenum WE 51-20 F3 was incubated briefly with [14C] valine and extracts of the mycelium were examined for the presence of peptides containing cystine and valine, as well as for related sulphur compounds. The isolation of a tripeptide which contains [alpha] -aminoadipic acid, cysteic acid [formed from cyst(e)ine during the isolation procedure, which involved oxidation with performic acid] and valine is described. After oxidation with performic acid mycelial extracts also contained cysteic acid, penicillaminic acid (derived from penicillin) and oxidized glutathione (GSO3H).Keywords
