Quinol oxidase encoded by cyoABCD in Rhizobium etli CFN42 is regulated by ActSR and is crucial for growth at low pH or low iron conditions.

Microbiology (Reading, England) - 1 Sept 2015

Lunak Zachary R, Dale Noel K

Abstract excerpt

Rhizobium etli aerobically respires with several terminal oxidases. The quinol oxidase (Cyo) encoded by cyoABCD is needed for efficient adaptation to low oxygen conditions and cyo transcription is upregulated at low oxygen. This study sought to determine how transcription of the cyo operon is regulated. The 5' sequence upstream of cyo was analysed in silico and revealed putative binding sites for ActR of the...
