Biosynthesis of isoleucine and valine in Rhodopseudomonas spheroides: regulation of threonine deaminase activity.

G J Barrtt.   

Abstract

The activities of threonine deaminase, acetohydroxy acid synthetase, acetohydroxy acid reductoisomerase, dihydroxy acid dehydrase, and transaminase B were detected in cell-free extracts of Rhodopseudomonas spheroides. No significant repression or derepression of threonine deaminase activity was observed.
