Nucleotide sequence and expression in Escherichia coli of the Lactococcus lactis citrate permease gene.

abstract：:The chb operon of Escherichia coli is involved in the utilization of the β-glucosides chitobiose and cellobiose. The function of chbG (ydjC), the sixth open reading frame of the operon that codes for an evolutionarily conserved protein is unknown. We show that chbG encodes a monodeacetylase that is essential for growt...
