merA, mercuric reductase from Serratia marcescens

Overview

Mercury resistant genemerA encodes a a mercuric ion reductase (MerA) that catalyze the reduction of mercuric ion(Hg2+) to the relative inert, volatile monoatomic mercury (Hg0) in a NADPH dependent reaction. 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.
