Reaction: NSUN2 methylates cytidine-34, cytidine-48 of unspliced tRNA(Leu)(CAA)
- in pathway: tRNA modification in the nucleus and cytosol
NSUN2 transfers a methyl group from S-adenosylmethionine to the 5 positions of cytidine-34 and cytidine-48 in tRNA(Leu)(CAA) (Brzezicha et al. 2006, Auxilien et al. 2012, Squires et al. 2012, Khoddami and Cairns 2013). Methylation of cytidine-34 occurs on the uspliced precursor tRNA(Leu)(CAA) (Brzezicha et al. 2006, Auxilien et al. 2012); methylation of cytidine-48 occurs on either the spliced or unspliced tRNA(Leu)(CAA) (Auxilien et al. 2012).
