ENZYME entry: EC 2.1.1.375

Accepted Name

NNS virus cap methyltransferase

Reaction catalysed

a 5'-end (5'-triphosphoguanosine)-adenylyl-adenylyl-cytidylyl-adenosine in mRNA + 2 S-adenosyl-L-methionine <=> a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-(2'-O-methyladenylyl)-adenylyl-cytidylyl-adenosine in mRNA + H(+) + 2 S-adenosyl-L-homocysteine

Comment(s)

The enzyme from non-segmented negative strain (NNS) viruses (e.g. rhabdoviruses) catalyzes two successive methylations.
In higher eukaryotes the two methylations occur in the reverse order and are catalyzed by two different enzymes (cf. EC 2.1.1.56 and EC 2.1.1.57) that do not required a specific motif.
