Substrate binding to EcTrmD is in rapid equilibrium to form the enzyme-tRNA-S-adenosyl-L-methionine complex, a proton abstraction step is rate limiting in methyl transfer 735927
Display the word mapDisplay the reaction diagram Show all sequences 2.1.1.228S-adenosyl-L-methionine + guanine37 in tRNA = S-adenosyl-L-homocysteine + N1-methylguanine37 in tRNA mechanism by which TrmD binds the substrate tRNA in an S-adenosyl-L-methionine-dependent manner: The trefoil-knot center, which is structurally conserved among SPOUTMTases, accommodates the adenosine moiety of S-adenosyl-L-methionine by loosening/retightening of the knot. The TrmD-specific regions surrounding the trefoil knot recognize the methionine moiety of S-adenosyl-L-methionine, and thereby establish the entire TrmD structure for global interactions with tRNA and sequential and specific accommodations of G37 and G36, resulting in the synthesis of m1G37-tRNA -, 737174
