FIGURE 8.
Acylation of glycerophosphoethanolamine. Shown is incorporation of 14C activity from [14C]choline-labeled GPC (0.5 mm) or [14C]ethanolamine-labeled GPE (0.5 mm) into chloroform-soluble lipids in the presence of 18:1-CoA (0.4 mm). Shown are microsomal preparations (40 μg of protein) of ale1Δ gpc1Δ yeast cells with overexpressed GPC1 or EV. The radioactivity resided in LPC in assays with added [14C]GPC and in lysophosphatidylethanolamine in the case of added [14C]GPE. Incubation time was 20 min, and the temperature was 30 °C. Data are given for triplicate assays ± S.D. (error bars).
