Abstract

The effect of the merD gene on the expression of the mer operon was determined from the rates of accumulation of merA-lacZ fusion protein in the presence and absence of an active merD gene in trans. In the presence of the merD gene, beta-galactosidase activity was 2- to 4-fold lower. The merD gene was cloned in a T7 promoter expression vector and the MerD protein product was visualized by autoradiography.
