Protein
Fumarate and nitrate reduction regulatory protein
Gene
fnr, SF1836, S1434
Organism
Shigella flexneri
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Global transcription factor that controls the expression of over 100 target genes in response to anoxia. It facilitates the adaptation to anaerobic growth conditions by regulating the expression of gene products that are involved in anaerobic energy metabolism. When the terminal electron acceptor, O2, is no longer available, it represses the synthesis of enzymes involved in aerobic respiration and increases the synthesis of enzymes required for anaerobic respiration By similarity.

Cofactori

Binds 1 4Fe-4S cluster per subunit By similarity.
