RC STRAIN=ATCC BAA-1151 / DSM 17278 / SZ; RG US DOE Joint Genome Institute; RA Lucas S., Copeland A., Lapidus A., Glavina del Rio T., Dalin E., RA Tice H., Bruce D., Goodwin L., Pitluck S., Chertkov O., Meincke L., RA Brettin T., Detter J.C., Han C., Tapia R., Kuske C.R., Schmutz J., RA Larimer F., Land M., Hauser L., Kyrpides N., Mikhailova N., Sung Y., RA Fletcher K.E., Ritalahti K.M., Loeffler F.E., Richardson P.; RT "Complete sequence of chromosome of Geobacter lovleyi SZ."; RL Submitted (MAY-2008) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the ATP-dependent amination of UTP to CTP with CC either L-glutamine or ammonia as the source of nitrogen (By CC similarity). CC -!- CATALYTIC ACTIVITY: ATP + UTP + NH(3) = ADP + phosphate + CTP. CC -!- ENZYME REGULATION: Allosterically activated by GTP, when glutamine CC is the substrate. Inhibited by CTP (By similarity). CC -!- PATHWAY: Pyrimidine metabolism; CTP biosynthesis via de novo CC pathway; CTP from UDP: step 2/2. CC -!- SUBUNIT: Homotetramer (By similarity). CC -!- SIMILARITY: Belongs to the CTP synthase family. CC -!- SIMILARITY: Contains 1 glutamine amidotransferase type-1 domain.
