-
when the mutant protein is the sole source of Spb1p in the cell (strain YBL4637), it leads to a severe growth defect with a generation time of about 300 min. No formation of 2'-O-methylguanosine2922
additional information
a point mutation in the Ado-Met binding site of Spb1p affects cell growth but does not abolish methylation of U2918. When this mutation is combined with disruption of snR52 cell growth is severely impaired and U2918 is no longer methylated. In vitro, Spb1p is able to methylate U2918 on 60S subunits. For this methylation two mechanisms coexist: a site-specific methyltransferase (Spb1p) and a snoRNA-dependent mechanism
