TL;DR

Results suggest that gcvA encodes a positive-acting regulatory protein that acts in trans to increase expression of gcv.

Abstract

A new mutation in Escherichia coli, designated gcvA1, that results in noninducible expression of both gcv and a gcvT-lacZ gene fusion was isolated. A plasmid carrying the wild-type gcvA gene complemented the mutation and restored glycine-inducible gcv and gcvT-lacZ gene expression. These results suggest that gcvA encodes a positive-acting regulatory protein that acts in trans to increase expression of gcv.
