RRNA (guanine-N2-)-methyltransferase

In enzymology, a rRNA (guanine-N2-)-methyltransferase (EC number|2.1.1.52) is an enzyme that catalyzes the chemical reaction

:S-adenosyl-L-methionine + rRNA $ightleftharpoons$ S-adenosyl-L-homocysteine + rRNA containing N₂-methylguanine

Thus, the two substrates of this enzyme are S-adenosyl methionine and rRNA, whereas its two products are S-adenosylhomocysteine and rRNA containing N2-methylguanine.

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:rRNA (guanine-N2-)-methyltransferase. Other names in common use include ribosomal ribonucleate guanine-2-methyltransferase, and S-adenosyl-L-methionine:rRNA (guanine-2-N-)-methyltransferase.

tructural studies
