Coding for the trans-acting regulator SmtB
In 1993, Huckle and co-workers reported the isolation and analysis of the smt locus from Synechococcus elongates PCC7942. Gene smtB, one of the components of the locus, encodes a transcriptional repressor of gene smtA, with which is required for normal tolerance to Zn2+ and Cd2+. The product of smtB functions by binding to the smt operator-promoter(smtO-P) and dissociating in the presence of Zn2+ there are four potential metal binding sites on protein SmtB as known as α3, α3N, α5 and α5C [9], different from Zn2+ resistance mechanisms, Cd2+ binds SmtB at the site α3N [10]. These two mechanisms both cause the elevated expression of smtA.
