RT "A metagenomic investigation of the 'star' freshwater diatom Asterionella
RT formosa and its bacterial cohort.";
RL Submitted (JUN-2017) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Transfers and isomerizes the ribose moiety from AdoMet to the
CC 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give
CC epoxyqueuosine (oQ-tRNA). {ECO:0000256|HAMAP-Rule:MF_00113}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=7-aminomethyl-7-carbaguanosine(34) in tRNA + S-adenosyl-L-
CC methionine = adenine + epoxyqueuosine(34) in tRNA + 2 H(+) + L-
CC methionine; Xref=Rhea:RHEA:32155, Rhea:RHEA-COMP:10342, Rhea:RHEA-
CC COMP:18582, ChEBI:CHEBI:15378, ChEBI:CHEBI:16708, ChEBI:CHEBI:57844,
CC ChEBI:CHEBI:59789, ChEBI:CHEBI:82833, ChEBI:CHEBI:194443;
CC EC=2.4.99.17; Evidence={ECO:0000256|HAMAP-Rule:MF_00113};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_00113}.
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_00113}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00113}.
CC -!- SIMILARITY: Belongs to the QueA family. {ECO:0000256|HAMAP-
CC Rule:MF_00113}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
