UniProtKB - P42707 (NISK_LACLL)
Protein
Nisin biosynthesis sensor protein NisK
Gene
nisK
Organism
Lactococcus lactis subsp. lactis (Streptococcus lactis)
Status
Functioni
Member of the two-component regulatory system NisK/NisR involved in the regulation of the biosynthesis of lantibiotic nisin. NisK may function as a membrane-associated protein kinase that phosphorylates NisR in response to environmental signals.
Catalytic activityi
- ATP + protein L-histidine = ADP + protein N-phospho-L-histidine. EC:2.7.13.3
GO - Molecular functioni
- ATP binding Source: UniProtKB-KW
- phosphorelay sensor kinase activity Source: InterPro
