Nucleotide sequence of the Serratia marcescens threonine operon and analysis of the threonine operon mutations which alter feedback inhibition of both aspartokinase I and homoserine dehydrogenase I.

Abstract excerpt

The nucleotide sequence of the Serratia marcescens threonine operon (thrA1A2BC) was determined. Three long open reading frames were identified; these open reading frames code for aspartokinase I (AKI)-homoserine dehydrogenase I (HDI), homoserine kinase, and threonine synthase, in that order. The...
