Lipid droplets (LDs) are cell compartments specialized for oil storage. Although their role and biogenesis are relatively well documented in seeds, little is known about their composition, structure and function in senescing leaves where they also ac

Lyso-Phosphatidic Acid Acyl-Transferases: a link with intracellular protein transport in Arabidopsis root cells?

Autor: Dittrich-Domergue F, Jean-Jacques Bessoule, Le-Guedard M, Lilly Maneta-Peyret, Patrick Moreau, Wattelet-Boyer, Yohann Boutté, Kriechbaumer

Phosphatidic acid (PA) and Lysophosphatidic acid acyltransferases (LPAATs) might be critical for the secretory pathway. Four extra-plastidial LPAATs (numbered 2,3,4 and 5) were identified in A. thaliana. These AtLPAATs, displaying an enzymatic activi

Lyso-lipid acyltransferases are enzymes involved in various processes such as lipid synthesis and remodelling. Here, we characterized the activity of an acyltransferase from Arabidopsis thaliana (LPIAT). In vitro, this protein, expressed in Escherich
