Abstract

SUMMARY

elements carrying wild-type alleles of the methionine regulatory genes and have been transferred from to and mutants of , and the resulting heterogenotes tested for resistance to methionine analogues and for repressibility of cystathionase (one of the methionine biosynthetic enzymes). The wild-type alleles of both genes were dominant in both tests. Increased gene dosage was found to have no effect on the rate of uptake of [C]methionine by cell suspensions. Possible roles for the and gene products in the regulation of methionine synthesis are considered.
