This family matches three types of P-loop containing kinases: phosphoribulokinases [1], uridine kinases [2] and bacterial pantothenate kinases(CoaA) [3]. Arabidopsis and other organisms have a dual uridine kinase/uracil phosphoribosyltransferase protein where the N-terminal region consists of a UK domain and the C-terminal region of a UPRT domain [4].
