- S-adenozil-L-metionin + guanozin2922 u 27S pre-rRNK S-adenozil-L-homocistein + 2'-O-metilguanozin2922 u 27S pre-rRNK
Spb1p je za mesto specifična 2'-O-riboza RNK metiltransferaza, koja katalizuje formiranje 2'-O-metilguanozina2922, univerzalno konzerviranje pozicije katalutičkog centera ribozoma koji je esencijalan za translaciju.
