CRYSTAL STRUCTURE OF THE MUTATED TRNA-GUANINE TRANSGLYCOSYLASE (TGT)Y106F COMPLEXED WITH PREQ1

Template:ABSTRACT PUBMED 14523925

Function

[TGT_ZYMMO] Exchanges the guanine residue with 7-aminomethyl-7-deazaguanine in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr). After this exchange, a cyclopentendiol moiety is attached to the 7-aminomethyl group of 7-deazaguanine, resulting in the hypermodified nucleoside queuosine (Q) (7-(((4,5-cis-dihydroxy-2-cyclopenten-1-yl)amino)methyl)-7-deazaguanosine).[HAMAP-Rule:MF_00168]

About this Structure

1ozq is a 1 chain structure with sequence from "achromobacter_anaerobium"_(sic)_shimwell_1937 "achromobacter anaerobium" (sic) shimwell 1937. Full crystallographic information is available from OCA.
