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 molybdopterin.
