Summaries for QTRT1 Gene

Entrez Gene Summary for QTRT1 Gene

  • This gene encodes the catalytic subunit of tRNA-guanine transglycosylase. tRNA-guanine transglycosylase is a heterodimeric enzyme complex that plays a critical role in tRNA modification by synthesizing the 7-deazaguanosine queuosine, which is found in tRNAs that code for asparagine, aspartic acid, histidine and tyrosine. A pseudogene of this gene is located on the long arm of chromosome X. [provided by RefSeq, Feb 2012]

GeneCards Summary for QTRT1 Gene

QTRT1 (Queuine TRNA-Ribosyltransferase Catalytic Subunit 1) is a Protein Coding gene. Among its related pathways are tRNA processing and Gene Expression. Gene Ontology (GO) annotations related to this gene include queuine tRNA-ribosyltransferase activity. An important paralog of this gene is QTRT2.

UniProtKB/Swiss-Prot for QTRT1 Gene

  • Catalytic subunit of the queuine tRNA-ribosyltransferase (TGT) that catalyzes the base-exchange of a guanine (G) residue with queuine (Q) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr), resulting in the hypermodified nucleoside queuosine (7-(((4,5-cis-dihydroxy-2-cyclopenten-1-yl)amino)methyl)-7-deazaguanosine) (PubMed:11255023, PubMed:20354154). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1 of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming queuine, allowing a nucleophilic attack on the C1 of the ribose to form the product (By similarity).
