Protein carboxyl methylation in Saccharomyces cerevisiae: evidence for STE14-dependent and STE14-independent pathways.

Abstract

We incubated yeast cells (Saccharomyces cerevisiae) with the methyl donor S-adenosyl-L-[methyl-3H]methionine and then fractionated their cellular components by gel electrophoresis in sodium dodecyl sulfate. By analyzing gel slices for [3H]methyl esters by a vapor-phase diffusion assay, we detect major methyl-esterified species that migrate at apparent… (More)
