Two MerR homologues that affect copper induction of the Bacillus subtilis copZA operon.

Microbiology (Reading, England) - 1 Dec 2003

Gaballa Ahmed, Cao Min, Helmann John D

Abstract excerpt

Copper ions induce expression of the Bacillus subtilis copZA operon encoding a metallochaperone, CopZ, and a CPx-type ATPase efflux protein, CopA. The copZA promoter region contains an inverted repeat sequence similar to that recognized by the mercury-sensing MerR protein. To investigate the possible involvement of MerR homologues in copZA regulation, null mutations were engineered affecting each of four putative...
