Construction of Zn2+/Cd(2+)-tolerant cyanobacteria with a modified metallothionein divergon: further analysis of the function and regulation of smt.

Journal of industrial microbiology - 1 Jan 2000

Turner J S, Robinson N J, Gupta A

Abstract excerpt

This paper reports the (de novo) construction of mutants of Synechococcus PCC 7942 lacking the repressor (SmtB) of the metallothionein gene, smtA. These smtA+/B- cells are more tolerant to elevated [Zn2+] and [Cd2+] than cells containing an intact metallothionein divergon (smt). Previously selected (by step-wise adaptation) Cd(2+)-tolerant mutants contain additional copies of smtA and possibly other undetected...
