Incubation of purified cardiac sarcolemmal vesicles (SL) in the presence of S-adenosyl-L-methionine, a methyl donor for the enzymatic N-methylation of phosphatidylethanolamine (PE), increased the Ca2+-stimulated ATPase and ATP-dependent Ca2+ accumulation activities. Quantitative analysis of the methylated phospholipids revealed that maximal increase of Ca2+-pump activities was associated with predominant synthesis and intramembranal accumulation of phosphatidyl-N,N-dimethylethanolamine. The stimulation of SL Ca2+-pump activities was prevented by inhibitors of PE N-methylation such as S-adenosyl-L-homocysteine and methyl acetimidate hydrochloride. The results suggest a possible role of PE N-methylation in the regulation of Ca2+-transport across the heart SL membrane.
