    The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of [protein|9896B99346B0D3F6D57F57377DB253B46135A37A|Spo0F]
  • mainly active in the older, inner regions of a colony (with [protein|2111AC1AE49D1006E10DC127BF5B7A0327DE94A7|KinB]) [Pubmed|21097618]
  • ATP + protein L-histidine --> ADP + protein N-phospho-L-histidine (according to UniProt)

    • [SW|Domains]

  • three tandem [SW|PAS domain]s in the N-terminal region of KinA, the [SW|second PAS] domain is the major N-terminal determinant of KinA dimerization [Pubmed|23504013]
  • the first [SW|PAS domain] is required for NAD(+) binding [Pubmed|23599347]
  • C-terminal histidine phosphotransferase domain

    • Modification

  • autophosphorylation on a His residue

    • Effectors of protein activity

  • interaction with [protein|5A5E17D39296FECC1C03B1A7791AB1065BB4E4DF|PxpB] or [protein|CEFD10FAFA0DBC83CD2B61DAC9339FEE025B1611|Sda] inhibits autophosphorylation of [protein|B29CAD04FB89ACC482EFCD29D50EDDA19145CAA2|KinA] [Pubmed|9334321,15023339]
  • autophosphorylation is inhibited by [protein|E5E2994D96FCECEE75E15136A08308C7B6C1C183|SivA] and [protein|E06A3392E644FEDC6F46ED41BBE89168F59B76B3|BslA] [Pubmed|23335417]
  • activated by interaction with NAD(+) that indicated poor respiratory activity of the cell [Pubmed|23599347], this has been falsified [pubmed|28449380]
