  4.6.1.17 | physiological function |
expression of genes moaABC of Escherichia coli results in accumulation of a pteridine named compound Z, an intermediate in biosynthesis of molydopterin. The carbon atoms of a pentose or pentulose are diverted to the ring atoms C6 and C7 and to the side chain atoms C2', C3' and C4' of compound Z. Carbon atom C1' of compound Z is derived from carbon atom C8 of a guanine derivative |

| 4.6.1.17 | physiological function |
in molybdopterin biosynthesis, a guanosine derivative serves as the initial biosynthetic precursor. Both the ribose and ring carbon atoms of the guanosine are utilized in this synthesis. The C-8 carbon of the guanosine precursor is retained and incorporated as the first carbon of the molybdopterin side chain |

| 4.6.1.17 | physiological function |
the physiological function of MoaA is the conversion of GTP to (8S)-3',8-cyclo-7,8-dihydroguanosine 5'-triphosphate (GTP 3?,8-cyclase), and that of MoaC is to catalyze the rearrangement of (8S)-3',8-cyclo-7,8-dihydroguanosine 5'-triphosphate into cyclic pyranopterin |
