Legend: Arabidopsis mitochondria can channel 3-hydroxy-14:0-ACP into lipopolysaccharide via a pathway homologous to the E. coli Lipid A pathway at least as far as Lipid IVA . Lipid IVA is further metabolized by a homolog to LpxK, which in E. coli incorporates 3-deoxy-D-manno-octulosonic acid (Kdo) moieties, but products of this enzyme have not yet been detected in Arabidopsis.
Abbreviations: LpxA, UDP-N-acetylglucosamine acyltransferase; LpxB, Lipid-A-disaccharide synthase; LpxC, UDP-3-O-acyl N-acetylglucosamine deacetylase; LpxD, UDP-3-O-(3-hydroxymyristoyl)glucosamine N-acyltransferase; LpxH, UDP-2,3-diacylglucosamine pyrophosphatase; LpxK, tetraacyl-disaccharide 4â-kinase; KdtA, 3-deoxy-D-manno-octulosonic acid (Kdo) transferase.
