Cyclic pyranopterin monophosphate synthase (EC 4.1.99.18, MOCS1A, MoaA, MoaC, molybdenum cofactor biosynthesis protein 1) is an enzyme with systematic name GTP 8,9-lyase (cyclic pyranopterin monophosphate-forming).[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction
- GTP cyclic pyranopterin monophosphate + diphosphate
This enzyme catalyses an early step in the biosynthesis of the molybdenum cofactor.
