Model of the interaction between the glyQS leader RNA and tRNAGly. Direct interactions between the Specifier Loop and the tRNA anticodon (1) and between the antiterminator bulge and tRNA acceptor end (3) have been demonstrated by genetic, biochemical and structural approaches. The interaction between the Stem I terminal loop and the tRNA elbow region (2) is indicated by structural evidence, and the residues that participate in this interaction in glyQS are not conserved in all T box leaders, suggesting that this interaction may vary in different genes. No structural information is available for Stem III, or the Stem II and IIA/B pseudoknot domains that are absent from glyQS leader RNAs (modified from [36]).
