| Nsun6 | tRNA (cytosine(72)-C(5))-methyltransferase NSUN6; S-adenosyl-L-methionine-dependent methyltransferase that specifically methylates the C5 position of cytosine 72 in tRNA(Thr)(TGT) and tRNA(Cys)(GCA). In vitro also methylates tRNA(Thr)(AGT). Methylation requires, in the acceptor stem region, the presence of the 3'-CCA terminus, the target site C72, the discriminator base U73, and the second and third base pairs (2:71 and 3:70) in the tRNA substrates. (476 aa) | ||||
| Gtpbp4 | Nucleolar GTP-binding protein 1; Involved in the biogenesis of the 60S ribosomal subunit. (634 aa) | ||||
