tRNA N(3)-methylcytidine methyltransferase METTL6 isoform X3 [Homo sapiens]

Protein Classification

class I SAM-dependent methyltransferase( domain architecture ID 10117436)

class I SAM-dependent methyltransferase catalyzes the methylation of one or more specific substrates using S-adenosyl-L-methionine (SAM or AdoMet) as the methyl donor; similar to METTL6, which contributes to post-transcriptional methylation of cytidine (formation of 3-methylcytidine) in tRNA; METTL6 interacts with seryl-tRNA synthetase and methylates tRNA(Ser);

 70-142 1.51e-07

S-adenosylmethionine-dependent methyltransferases (SAM or AdoMet-MTase), class I; AdoMet-MTases are enzymes that use S-adenosyl-L-methionine (SAM or AdoMet) as a substrate for methyltransfer, creating the product S-adenosyl-L-homocysteine (AdoHcy). There are at least five structurally distinct families of AdoMet-MTases, class I being the largest and most diverse. Within this class enzymes can be classified by different substrate specificities (small molecules, lipids, nucleic acids, etc.) and different target atoms for methylation (nitrogen, oxygen, carbon, sulfur, etc.).
