Arabidopsis thaliana At2g33470 encodes a glycolipid transfer protein (GLTP) that enhances the intervesicular trafficking of glycosphingolipids in vitro. GLTPs have previously been identified in animals and fungi but not in plants. Thus, At2g33470 is the first identified plant GLTP and we have
The structure and biosynthetic route for an unidentified lipid (lipid X) detected by TLC of cabbage (Brassica oleracea) lipids was determined. Lipid X is a phospholipid that is resistant to mild alkali and detectable by MALDI-TOF MS as an adduct with Phos-tag, a phosphate-capture zinc complex.
Aminophospholipid ATPases (ALAs) are lipid flippases involved in transporting specific lipids across membrane bilayers. Arabidopsis thaliana contains 12 ALAs in five phylogenetic clusters, including four in cluster 3 (ALA4, -5, -6, and -7). ALA4/5 and ALA6/7 are expressed primarily in vegetative
