DE RecName: Full=Probable molybdenum cofactor biosynthesis protein A; DE Flags: Fragment; GN Name=moaA; OS Methanobacterium thermoautotrophicum (strain Marburg / DSM 2133). OC Archaea; Euryarchaeota; Methanobacteria; Methanobacteriales; OC Methanobacteriaceae; Methanothermobacter. OX NCBI_TaxID=79929; RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC DNA]. RX MEDLINE=96163477; PubMed=8575452; RX DOI=10.1111/j.1432-1033.1995.910_a.x; RA Hochheimer A., Schmitz R.A., Thauer R.K., Hedderich R.; RT "The tungsten formylmethanofuran dehydrogenase from Methanobacterium RT thermoautotrophicum contains sequence motifs characteristic for RT enzymes containing molybdopterin dinucleotide."; RL Eur. J. Biochem. 234:910-920(1995). CC -!- FUNCTION: Together with moaC, is involved in the conversion of a CC guanosine derivative (5'-GTP) into molybdopterin precursor Z (By CC similarity). CC -!- COFACTOR: Binds 2 4Fe-4S clusters. Binds 1 4Fe-4S cluster CC coordinated with 3 cysteines and an exchangeable S-adenosyl-L- CC methionine and 1 4Fe-4S cluster coordinated with 3 cysteines and CC the GTP-derived substrate (By similarity). CC -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis. CC -!- SIMILARITY: Belongs to the radical SAM superfamily. MoaA family.
