MeSH Heading: Uroporphyrinogen III Synthetase
Tree Number(s): D08.811.520.241.300.950
Unique ID: D014576
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D014576
Scope Note: An enzyme that catalyzes the cyclization of hydroxymethylbilane to yield UROPORPHYRINOGEN III and water. It is the fourth enzyme in the 8-enzyme biosynthetic pathway of HEME, and is encoded by UROS gene. Mutations of UROS gene result in CONGENITAL ERYTHROPOIETIC PORPHYRIA.
Entry Term(s): Cosynthase; Uroporphyrinogen III Cosynthetase; Uroporphyrinogen Isomerase; Uroporphyrinogen-III Synthase
