P.18 right column 4th paragraph: "The lipid composition of oleate-grown S. cerevisiae peroxisomes has been determined by Zinser et al. (primary source). The peroxisomal membrane contains the major cellular phospholipids—phosphatidylcholine (48.2%), phosphatidylethanolamine (22.9%), and phosphatidylinositol (15.8%)—but also has a remarkably high cardiolipin content (7%). The relative abundance of cardiolipin is noteworthy since this lipid is synthesized in mitochondria (Henry et al. 2012). The other lipids are derived from the ER-however, the mechanisms by which these lipids reach the peroxisomes are not yet firmly established-some evidence suggests that this process involves vesicular transport both from the ER and from mitochondria (Braschi et al. 2010)." |
