Protein prenylation in Schizosaccharomyces pombe.
S. pombe is shown to be a powerful system for studies concerning attachment of polyisoprenoid moieties to proteins, due to its ability to take up exogenous mevalonic acid efficiently. The fission yeast can take up about 5% of the exogenously added mevalonic acid and incorporate approximately 10% of this into protein. By contrast, the uptake obtained with the budding yeast S. cerevisiae is less than 0.5%. HPLC analysis of total S. pombe protein-bound isoprenoids revealed that approximately 55% of the counts co-migrated with the geranylgeraniol standard, while approximately 45% of the counts co-migrated with farnesol. We could not detect any effects of mevinolin or other HMG-CoA reductase inhibitors in S. pombe.
