Establishes in Cupriavidus metallidurans CH34 (formerly Alcaligenes eutrophus CH34) that czcI is transcribed as a 400-nucleotide transcript and as part of the czcNIC-czcCBA heavy-metal homeostasis determinant induced by Zn2+, Co2+, and Cd2+.
"Induction of czcN, czcI, czcCBA, and czcDRS followed a similar pattern: transcription was induced best by 300 microM zinc, less by 300 microM cobalt, and only slightly by 300 microM cadmium."
