name: nitrate/nitrite sensor protein NarQ isoform 1 phosphorylated 1
def: "A nitrate/nitrite sensor protein NarQ isoform 1 that has been phosphorylated by autocatalysis on a His residue within the histidine kinase domain, in response to environmental signals. Example: UniProtKB:P27896-1, His-370, MOD:00890." [PMID:19968795, EcoCyc:PHOSPHO-NARQ]
comment: Category=modification. Note: This proteoform phosphorylates narP, which in turns controls the transcriptional expression of several genes involved in anaerobic respiration and increases the affinity for its specific DNA binding sites.
