RT "The Genome Sequence of Enterococcus gilvus ATCC BAA-350.";
RL Submitted (FEB-2013) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the conversion of epoxyqueuosine (oQ) to queuosine
CC (Q), which is a hypermodified base found in the wobble positions of
CC tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr).
CC {ECO:0000256|ARBA:ARBA00002268, ECO:0000256|HAMAP-Rule:MF_02089}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + epoxyqueuosine(34) in tRNA = A + H2O + queuosine(34) in
CC tRNA; Xref=Rhea:RHEA:32159, Rhea:RHEA-COMP:18571, Rhea:RHEA-
CC COMP:18582, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:17499,
CC ChEBI:CHEBI:194431, ChEBI:CHEBI:194443; EC=1.17.99.6;
CC Evidence={ECO:0000256|ARBA:ARBA00035072, ECO:0000256|HAMAP-
CC Rule:MF_02089};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000256|ARBA:ARBA00004691, ECO:0000256|HAMAP-Rule:MF_02089}.
CC -!- SIMILARITY: Belongs to the QueH family. {ECO:0000256|ARBA:ARBA00008207,
CC ECO:0000256|HAMAP-Rule:MF_02089}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
