HAMP (Histidine kinases, Adenylyl cyclases, Methyl binding proteins, Phosphatases) domain
SMART accession number:SM00304
Description: -
Interpro abstract (IPR003660):

The HAMP domain (present in Histidine kinases, Adenyl cyclases, Methyl-accepting proteins and Phosphatases) is an approximately 50-amino acid alpha-helical region. It is found in bacterial sensor and chemotaxis proteins and in eukaryotic histidine kinases. The bacterial proteins are usually integral membrane proteins and part of a two-component signal transduction pathway. One or several copies of the HAMP domain can be found in association with other domains, such as the histidine kinase domain, the bacterial chemotaxis sensory transducer domain, the PAS repeat, the EAL domain, the GGDEF domain, the protein phosphatase 2C-like domain, the guanylate cyclase domain, or the response regulatory domain. It has been suggested that the HAMP domain possesses a role of regulating the phosphorylation or methylation of homodimeric receptors by transmitting the conformational changes in periplasmic ligand-binding domains to cytoplasmic signalling kinase and methyl-acceptor domains [ (PUBMED:10418137) ].
