Abstract
In a strain of E. coli K-12 lacking threonine deaminase, the enzyme converting .alpha.-ketoisovalerate and .alpha.-keto-.beta.-methylvalerate to valine and isoleucine, respectively, was multivalently repressed by valine, isoleucine and leucine. This activity was due to transaminase B, specified by the ilvE structural gene.This publication has 13 references indexed in Scilit:
