Abstract

Dedicated to Professor Dieter Seebach on the occasion of his 70th birthday tRNA-Guanine transglycosylase (TGT, EC 2.4. 2.29) is a tRNA-modifying enzyme common to nearly all organisms including humans.[1] In bacteria, TGT catalyzes the exchange of guanine in position 34 by preQ1, whereas eukaryotic TGT accelerates the replacement by queuine.[2] This difference in substrate specificity offers the possibility for selective inhibition of the ...
