Clan: His_Kinase_A (CL0025)

Summary

His Kinase A (phospho-acceptor) domain Add an annotation

This is the dimerisation and phospho-acceptor domain of a sub-family of histidine kinases. It shares sequence similarity with Pfam:PF00512 and Pfam:PF07536. It is usually found adjacent to a C-terminal ATPase domain (Pfam:PF02518). This domain is found in a wide range of Bacteria and also several Archaea. It comprises one of the fundamental units of the two-component signal transduction system [2-7].

This clan contains 9 families and the total number of domains in the clan is 890078. The clan was built by DJ Studholme.

Structures

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
