RPSBLAST alignment for GI: 254780178 and conserved domain: pfam01702

>gnl|CDD|145056 pfam01702, TGT, Queuine tRNA-ribosyltransferase. This is a family of queuine tRNA-ribosyltransferases EC:2.4.2.29, also known as tRNA-guanine transglycosylase and guanine insertion enzyme. Queuine tRNA-ribosyltransferase modifies tRNAs for asparagine, aspartic acid, histidine and tyrosine with queuine. It catalyses the exchange of guanine-34 at the wobble position with 7-aminomethyl-7-deazaguanine, and the addition of a cyclopentenediol moiety to 7-aminomethyl-7-deazaguanine-34 tRNA; giving a hypermodified base queuine in the wobble position. The aligned region contains a zinc binding motif C-x-C-x2-C-x29-H, and important tRNA and 7-aminomethyl-7deazaguanine binding residues. Length = 238
 Score =  321 bits (825), Expect = 2e-88
 Identities = 131/233 (56%), Positives = 162/233 (69%)
