ID D2NPM3_ROTMD Unreviewed; 466 AA. AC D2NPM3; DT 02-MAR-2010, integrated into UniProtKB/TrEMBL. DT 02-MAR-2010, sequence version 1. DT 19-FEB-2014, entry version 31. DE RecName: Full=Queuine tRNA-ribosyltransferase; DE EC=2.4.2.29; DE AltName: Full=Guanine insertion enzyme; DE AltName: Full=tRNA-guanine transglycosylase; GN Name=tgt; OrderedLocusNames=RMDY18_17590; OS Rothia mucilaginosa (strain DY-18) (Stomatococcus mucilaginosus). OC Bacteria; Actinobacteria; Actinobacteridae; Actinomycetales; OC Micrococcineae; Micrococcaceae; Rothia. OX NCBI_TaxID=680646; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=DY-18; RA Yamane K., Nambu T., Mashimo C., Sugimori C., Yamanaka T., Leung K., RA Fukushima H.; RT "Complete genome sequence of Rothia mucilaginosa DJ."; RL Submitted (JUL-2009) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Exchanges the guanine residue with 7-aminomethyl-7- CC deazaguanine in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His CC and -Tyr). After this exchange, a cyclopentendiol moiety is CC attached to the 7-aminomethyl group of 7-deazaguanine, resulting CC in the hypermodified nucleoside queuosine (Q) (7-(((4,5-cis- CC dihydroxy-2-cyclopenten-1-yl)amino)methyl)-7-deazaguanosine) (By CC similarity). CC -!- CATALYTIC ACTIVITY: Guanine(34) in tRNA + 7-aminomethyl-7- CC carbaguanine = 7-aminomethyl-7-carbaguanine(34) in tRNA + guanine. CC -!- CATALYTIC ACTIVITY: Guanine(34) in tRNA + queuine = queuosine(34) CC in tRNA + guanine. CC -!- COFACTOR: Binds 1 zinc ion per subunit (By similarity). CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis. CC -!- SIMILARITY: Belongs to the queuine tRNA-ribosyltransferase family.
