CTPS This enzyme is involved in the de novo synthesis of CTP, a precursor of DNA, RNA and phospholipids. Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as a source of nitrogen. This enzyme and its product, CTP, play a crucial role in the proliferation of activated lymphocytes and therefore in immunity. Belongs to the CTP synthase family. Widely expressed. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
