Mechanisms of oxygen inhibition of nirK expression in Rhodobacter sphaeroides.

Microbiology (Reading, England) - 1 Oct 2010

Hartsock Angela, Shapleigh James P

Abstract excerpt

R. sphaeroides strain 2.4.3, when lacking the cbb(3) oxidase, is unable to transition from aerobic respiration to denitrification using cellular respiration as a means of reducing oxygen levels. This is due to an inability to express nirK, the gene encoding nitrite reductase. Under certain photosynthetic conditions this strain can transition from aerobic to nitrate respiration, demonstrating that nirK expression...
