Ligands: 21W, ACT, GOL, SO4 Related: 4mcc Gene: HI_0202, trmD (HAEIN) Activity: tRNA (guanine(37)-N(1))-methyltransferase, with EC number 2.1.1.228 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [TRMD_HAEIN] Specifically methylates guanosine-37 in various tRNAs (By similarity).[HAMAP-Rule:MF_00605] Publication Abstract from PubMed The t-RNA-(N1G37) methyl transferase (TrmD) is essential for growth and highly conserved in both Gram-positive and Gram-negative bacterial pathogens. Additionally, TrmD is very distinct from its human ortholog TRM5, and thus is a suitable target for the design of novel antibacterials. Screening of a collection of compound fragments using Haemophilus influenzae TrmD identified inhibitory, fused thieno-pyrimidones that were competitive with S-adenosylmethionine (SAM), the physiological methyl donor substrate. Guided by x-ray co-crystal structures, fragment 1 was elaborated into a nanomolar inhibitor of a broad range of Gram-negative TrmD isozymes. These compounds demonstrated no activity against representative human SAM utilizing enzymes, PRMT1 and SET7/9. This is the first report of selective, nanomolar inhibitors of TrmD with demonstrated ability to order the TrmD lid in the absence of tRNA.
