RL Submitted (NOV-2023) to UniProtKB.
CC -!- FUNCTION: Probable component of the wybutosine biosynthesis pathway.
CC Wybutosine is a hyper modified guanosine with a tricyclic base found at
CC the 3'-position adjacent to the anticodon of eukaryotic phenylalanine
CC tRNA. Catalyzes the condensation of N-methylguanine with 2 carbon atoms
CC from pyruvate to form the tricyclic 4-demethylwyosine, an intermediate
CC in wybutosine biosynthesis. {ECO:0000256|ARBA:ARBA00025368}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N(1)-methylguanosine(37) in tRNA(Phe) + pyruvate + S-adenosyl-
CC L-methionine = 4-demethylwyosine(37) in tRNA(Phe) + 5'-deoxyadenosine
CC + CO2 + H2O + L-methionine; Xref=Rhea:RHEA:36347, Rhea:RHEA-
CC COMP:10164, Rhea:RHEA-COMP:10165, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:16526, ChEBI:CHEBI:17319,
CC ChEBI:CHEBI:57844, ChEBI:CHEBI:59789, ChEBI:CHEBI:64315,
CC ChEBI:CHEBI:73542; EC=4.1.3.44;
CC Evidence={ECO:0000256|ARBA:ARBA00000664};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|ARBA:ARBA00001966};
CC -!- PATHWAY: tRNA modification; wybutosine-tRNA(Phe) biosynthesis.
CC {ECO:0000256|ARBA:ARBA00004797}.
CC -!- SIMILARITY: Belongs to the TYW1 family.
CC {ECO:0000256|ARBA:ARBA00010115}.
