Enzyme Information
| 2.1.1.346 |
U6 snRNA m(6)A methyltransferase.
based on mapping to UniProt Q86W50
S-adenosyl-L-methionine + adenine in U6 snRNA = S-adenosyl-L-homocysteine + N(6)-methyladenine in U6 snRNA.
-!- This enzyme, found in vertebrates, methylates a specific adenine in a hairpin structure of snRNA. -!- The effects of the binding of the methyltransferase to its substrate is important for the regulation of the activity of an isoform of EC 2.5.1.6, that produces S-adenosyl-L-methionine. -!- The enzyme also binds (and maybe methylates) the lncRNAs XIST and MALAT1 as well as a number of pre-mRNAs at specific positions often found in the intronic regions.

| 2.1.1.348 |
mRNA m(6)A methyltransferase.
based on mapping to UniProt Q86W50
S-adenosyl-L-methionine + adenine in mRNA = S-adenosyl-L-homocysteine + N(6)-methyladenine in mRNA.
-!- This enzyme, found in eukaryotes, methylates adenines in mRNA with the consensus sequence RRACH.
