nrpR

Gene

nrpR

Protein

Global nitrogen regulator NrpR

Organism

Methanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440)

Length

542 amino acids

Function

Transcriptional repressor of nitrogen fixation and assimilation genes. Binds to two tandem operators in the glnA and nif promoters, thereby blocking transcription of the genes.

Similarity

Belongs to the NrpR family.

Mass

61.195 kDa
