L-Cysteine + molybdenum cofactor (Moco) + reduced electron acceptor → L-Alanine + Thio-molybdenum cofactor + Water + oxidized electron acceptor
Cyclic pyranopterin monophosphate (→) Transport: Arabidopsis thaliana, Cell, Mitochondrial Matrix to Arabidopsis thaliana, Cell, Cytosol
Guanosine triphosphate + S-Adenosylmethionine + reduced electron acceptor → 3',8-cH2GTP + 5'-Deoxyadenosine + Hydrogen Ion + L-Methionine + oxidized electron acceptor
3',8-cH2GTP → Cyclic pyranopterin monophosphate + Pyrophosphate
Cyclic pyranopterin monophosphate + Water → 4 Hydrogen Ion + Molybdopterin
Adenosine triphosphate + Hydrogen Ion + Molybdopterin → Molybdopterin-AMP + Pyrophosphate
Hydrogen Ion + Molybdate + Molybdopterin-AMP → Adenosine monophosphate + Water + molybdenum cofactor (Moco)
