Abstract

ABSTRACT The tutB gene, which lies just downstream of tpl , has been cloned from Erwinia herbicola , and its product was analyzed. Despite its high sequence similarity to tryptophan transporters, TutB was found to be a tyrosine-specific transporter. Tryptophan acted as a competitive inhibitor of tyrosine transport. Unlike the tryptophanase operon, the tpl and tutB genes do not constitute an operon.
