Abstract

THE cockroach and the Japanese beetle are able to utilize sulphate-S for the synthesis of methionine and cystine1. The German cockroach, Blattella germanica (L.), is also able to satisfy its sulphur requirements with homocystine, methionine sulphoxide, cysteic acid, taurine, and β-hydroxyethanesulphonic acid2. However, removal of the intracellular symbionts from the cockroach prevents incorporation of sulphate-S into cysteine and methionine3.
