HBM

helical bimodular (HBM) domain
HBM
SMART accession number:SM01358
Description: The HBM domain was identified in Bacteria and Archaea and forms part of chemoreceptors and histidine kinases. The domain was characterized by a bimodular architecture, where ligand binding to each module caused a chemotactic response. The conservation of amino acids in the ligand binding sites of both modules suggests that HBM family members recognize similar ligands. (PMID:24347303)
