Jr., Skatrud P.L., RA Glass J.I.; RT "Genome of the bacterium Streptococcus pneumoniae strain R6."; RL J. Bacteriol. 183:5709-5717(2001). CC -!- FUNCTION: Catalyzes the reversible phosphorylation of UMP to UDP CC (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + UMP = ADP + UDP. CC -!- ENZYME REGULATION: Allosterically activated by GTP. Inhibited by CC UTP (By similarity). CC -!- PATHWAY: Pyrimidine metabolism; CTP biosynthesis via de novo CC pathway; UDP from UMP (UMPK route): step 1/1. CC -!- SUBUNIT: Homohexamer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the UMP kinase family.
