| tryptophan synthase | <enzyme> An enzyme that catalyses the conversion of l-serine and 1-(indol-3-yl)glycerol 3-phosphate to l-tryptophan and glyceraldehyde 3-phosphate. It is a pyridoxal phosphate protein that also catalyses the conversion of serine and indole into tryptophan and water and of indoleglycerol phosphate into indole and glyceraldehyde phosphate. Chemical name: L-Serine hydro-lyase (adding indoleglycerol-phosphate) Registry number: EC 4.2.1.20 (12 Dec 1998) |

| farnesylgeranyl diphosphate synthase | <enzyme> A prenyltransferase which synthesises c25-prenyl diphosphate; distinct from geranylgeranyl diphosphate synthase (EC 2.5.1.29); can use geranylgeranyl diphosphate as a substrate Registry number: EC 2.5.1.- Synonym: fgpp synthase (26 Jun 1999) |
| UMP synthase | Uridine esterified by phosphoric acid on one or more sugar hydroxyl groups; UMP is typically uridine 5'-monophosphate; 2' and 3' derivatives also occur; precursor for the biosynthesis of other pyrimidine nucleotides. Synonym: UMP synthase, uridine 5'-monophosphate. Uridylic acid synthase, a bifunctional enzyme that contains the activities of both orotate phosphoribosyltransferase and orotidine-5'-monophosphate decarboxylase; catalyses a key step in pyrimidine biosynthesis; a deficiency of this enzyme leads to orotic aciduria.
