ArsR (or ArsR/SmtB) family metalloregulatory homodimeric repressors collectively respond to a wide range of metal ion inducers in regulating homeostasis and resistance of essential and nonessential metal ions in bacteria. BxmR from the cyanobacterium Osciliatoria brevis is the first characterized ArsR protein that senses both Cu (I)/Ag (I) and divalent metals Zn (II)/Cd (II) in cells by regulating the expression of a P-type ATPase efflux pump (Bxa1) and an intracellular metallothionein (BmtA… CONTINUE READING
