27S pre-rRNA (guanosine2922-2'-O)-methyltransferase (EC 2.1.1.167, Spb1p (gene), YCL054W (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:27S pre-rRNA (guanosine2922-2'-O-)-methyltransferase.[1][2] 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-rRNA

Spb1p is a site-specific 2'-O-ribose RNA methyltransferase that catalyses the formation of 2'-O-methylguanosine2922.
