KapB

SMART accession number:	SM01298
Description:	This bacterial protein forms an anti-parallel beta sheet with an extending alpha helical region.
Interpro abstract (IPR014916):	Kinase associated protein B (KapB) is one of the major histidine kinases that provide phosphate input in the phosphorelay to produce SpoOA approximately P, the key transcription factor controlling the initiation of sporulation in Bacillus subtilis [ (PUBMED:9426145) ]. It forms an anti-parallel beta sheet with an extending alpha helical region.
