A PF07475 Hpr_kinase_C HPr Serine kinase C-terminal domain Domain This family represents the C terminal kinase domain of Hpr Serine/threonine kinase PtsK. This kinase is the sensor in a multicomponent phosphorelay system in control of carbon catabolic repression in bacteria [1]. This kinase in unusual in that it recognises the tertiary structure of its target and is a member of a novel family unrelated to any previously described protein phosphorylating enzymes [1]. X-ray analysis of the full-length crystalline enzyme from Staphylococcus xylosus at a resolution of 1.95 A shows the enzyme to consist of two clearly separated domains that are assembled in a hexameric structure resembling a three-bladed propeller [2].
