27S pre-rRNA (guanosine2922-2′-O)-methyltransferase (EC 2.1.1.167 Spb1p (gene) YCL054W (gene)) is an enzyme with system name S-adenosyl-L-methionine:27S pre-rRNA (guanosine2922-2′-O-)-methyltransferase. This enzyme catalyses the following chemical reaction S-adenosyl-L-methionine + guanosine2922 in 27S pre-rRNA S-adenosyl-L-homocysteine + 2′-O-methylguanosine2922 in 27S pre-rRNASpb1p is a site-specific 2′-O-ribose RNA methyltransferase that catalyses the formation of 2′-O-methylguanosine2922.
