“In the presence of calcium an increment in phosphatidylethanolamine was observed with a concomitant decrease in phosphatidic acid fractions, whereas these modifications were not observed in the absence of calcium.”
“ Calcium also induces fusion and leakage of egg phosphatidylethanolamine large unilamellar vesicles containing cholesterol sulphate, but has no effect on fusion or leakage of egg phosphatidylcholine large unilamellar vesicles containing cholesterol sulphate.”
“The catalytic activity of the purified enzyme with phosphatidylcholine or phosphatidylethanolamine increased sharply in the presence of between 10(-7) and 10(-6) M calcium ion , indicating that it could be regulated by less than micromolar concentration of calcium.”
“Adding phosphatidylethanolamine and phosphatidylserine decreased the Ka for calcium to 2.0 +/- 0.9 microM with diolein and to 0.7 +/- 0.4 microM with TPA.”

“ Calcium ions induced tight binding of massive amounts of liposomes containing cardiolipin, phosphatidyl-ethanolamine and phosphatidylcholine to erythrocytes.”
“The results indicate that the cellular levels of ATP, CoA, pantetheine, magnesium, manganese, and calcium ions may all play a role in the regulation of phosphatidylethanolamine biosynthesis.”

“The monolayers of phosphatidylethanolamine and phosphatidylcholine bind small amounts of Ca 2 + when the lipid molecules are packed closer than 150 A 2 per molecule.”
“We reported that the relationship between distance and time in the proton movement was quadratic [4], that the conduction was sensitive to the strength of the buffer [4] and that the presence of Ca +* was inhibitory in the case of phosphatidylethanolamine [5].”
