Analysis of hemF gene function and expression in Rhodobacter sphaeroides 2.4.1

J Bacteriol. 2006 Jan;188(2):801-4. doi: 10.1128/JB.188.2.801-804.2006.

Abstract

The hemF gene of Rhodobacter sphaeroides 2.4.1 is predicted to code for an oxygen-dependent coproporphyrinogen III oxidase. We found that a HemF- mutant strain is unable to grow under aerobic conditions. We also determined that hemF expression is controlled by oxygen, which is mediated, at least in part, by the response regulatory protein PrrA.
