Protein
Probable transcription repressor NiaR
Organism
Thermotoga maritima (strain ATCC 43589 / MSB8 / DSM 3109 / JCM 10099)
Function
Probably functions to regulate transcription of NAD metabolic genes. Binds to DNA upstream of the probable nadBII/nadA/nadC and niaRP operons in a nicotinic acid dependent fashion. Nicotinic acid may be a corepressor.
