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.
catalyze the reduction of mercuric ion(Hg2+) to the relative inert, volatile monoatomic mercury (Hg0) in a NADPH dependent reaction. </p> merA is located downstream of merR (encodes for Mer Operon regulatory Mer Repressor) and two genes encode. for mercuric ion transport protein, MerB and MerT.
While orchestrating with the mercury transport system, MerA and <a href="https://parts.igem.org/Part:BBa_K1420002">MerB</a> are the key detoxification enzymes that confer mercury resistance.
