- MRNA (nucleoside-2'-O-)-methyltransferase
enzymology, a mRNA (nucleoside-2'-O-)-methyltransferase (EC number|188.8.131.52) is an enzymethat catalyzes the chemical reaction
:S-adenosyl-L-methionine + m7G(5')pppR-RNA S-adenosyl-L-homocysteine + m7G(5')pppRm-RNA (mRNA containing a 2'-O-methylpurine cap)
Thus, the two substrates of this enzyme are S-adenosyl methionine and
m7G(5')pppR-RNA, whereas its two products are S-adenosylhomocysteineand m7G(5')pppRm-RNA (mRNA containing a 2'-O-methylpurine cap).
This enzyme belongs to the family of
transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:mRNA (nucleoside-2'-O-)-methyltransferase. Other names in common use include messenger ribonucleate nucleoside 2'-methyltransferase, and messenger RNA (nucleoside-2'-)-methyltransferase.
CAS registry numberfor this enzyme class is CAS registry|61970-02-3."
