The tRNA methyltransferase 1 (TRMT1) enzyme catalyzes the formation of dimethylguanosine (m2,2G) in tRNAs. Loss-of-function mutations in TRMT1 lead to intellectual disability disorders in humans. In addition to TRMT1, vertebrates encode a tRNA methyltransferase 1-like (TRMT1L) paralog. Here, we use ...
