ATP:protein-L-histidine N-phosphotransferase
This entry has been included to accommodate those protein-histidine kinases for which the phosphorylation site has not been established (i.e. either the pros- or tele-nitrogen of histidine). A number of histones can act as acceptor.

one hybrid histidine kinase consisting of the BvgS transmitter and HPt domains and of the EvgS receiver domain BvgS-TO-EvgS-R is able to phosphorylate BvgA but not EvgA. In contrast, the hybrid protein consisting of the BvgS transmitter and the EvgS receiver and HPt domains BvgS-T-EvgS-RO is unable to phosphorylate BvgA but efficiently phosphorylates EvgA

-
TorS is a sensor that contains three phosphorylation sites and transphosphorylates TorR via a four-step phosphorelay, His443 to Asp723 to His850 to Asp(TorR). TorS can dephosphorylate phospho-TorR when trimethylamine N-oxide is removed. Dephosphorylation probably occurs by a reverse phosphorelay, Asp(TorR) to His850 to Asp723

the His residue at position 243 of the EnvZ protein is changed by means of site-directed mutagenesis. The mutant EnvZ protein is defective in its in vitro ability not only as to EnvZ-autophosphorylation but also OmpR-phosphorylation and OmpR-dephosphorylation. This particular mutant EnvZ protein seems to exhibit null functions as to the in vivo osmoregulatory phenotype
