1mu4 is a 2 chain structure with sequence from Bacillus subtilis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
CRH_BACSU Along with seryl-phosphorylated HPr, phosphorylated Crh is implicated in carbon catabolite repression (CCR) of levanase, inositol dehydrogenase, and beta-xylosidase. Exerts its effect on CCR by interacting with CcpA.[1][2]
