TRMD_HAEIN Specifically methylates guanosine-37 in various tRNAs (By similarity).[HAMAP-Rule:MF_00605]
Publication Abstract from PubMed
The deep trefoil knot architecture is unique to the SpoU and tRNA methyltransferase D (TrmD) (SPOUT) family of methyltransferases (MTases) in all three domains of life. In bacteria, TrmD catalyzes the N(1)-methylguanosine (m(1)G) modification at position 37 in transfer RNAs (tRNAs) with the (36)GG(37) sequence, using S-adenosyl-l-methionine (AdoMet) as the methyl donor. The m(1)G37-modified tRNA functions properly to prevent +1 frameshift errors on the ribosome. Here we report the crystal structure of the TrmD homodimer in complex with a substrate tRNA and an AdoMet analog. Our structural analysis revealed the mechanism by which TrmD binds the substrate tRNA in an AdoMet-dependent manner. The trefoil-knot center, which is structurally conserved among SPOUT MTases, accommodates the adenosine moiety of AdoMet by loosening/retightening of the knot. The TrmD-specific regions surrounding the trefoil knot recognize the methionine moiety of AdoMet, 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 m(1)G37-tRNA.
