NimR DNA-binding transcriptional repressor

Synonyms: NimR
NimR, formerly called YeaM, belongs to the AraC/XylS superfamily [3] It confers resistance to 2-nitroimidazole, an antibacterial and antifungal agent [1] NimR plays a regulatory role in divergent transcription of the nimT and nimR genes [1] NimR: regulator of nimT [1]
