merA, mercuric reductase from Serratia marcescens

Overview

Mercury resistant gene merA encodes a mercuric ion reductase, MerA, that couples with organomercurial lyase, MerB, to detoxify inorganic and organic mercury compound. While MerA and MerB are the key enzymes of mercury detoxification, they orchestrate with mercury transport proteins, MerT and MerP, to confer bacterial mercury resistance. Figure 1 shows the interactions of MerA and other proteins encoded by Mer Operon.

Function

MerA catalyzes the reduction of mercuric ion(Hg2+) to the relative inert, volatile monoatomic mercury (Hg0) in a NADPH dependent reaction. </p>
