WebIn enzymology, a beta-ketoacyl-acyl-carrier-protein synthase II ( EC 2.3.1.179) is an enzyme that catalyzes the chemical reaction. (Z)-hexadec-11-enoyl- [acyl-carrier … WebAbstract. Crude spinach leaf extract readily forms the stearoyl derivative of acyl-carrier-protein (ACP) when acetyl-ACP and malonyl-ACP are incubated together. Palmitoyl-ACP is also elongated by malonyl-ACP to stearoyl-ACP. When β-ketoacyl-ACP synthase {3-oxoacyl- [ACP] synthase; acyl- [ACP]:malonyl- [ACP] C -acyltransferase …
WebNevertheless, three genes for mitochondrial ACP have been detected in Arabidopsis. In addition, this plant has five deduced genes for plastid ACP [6]. Figure 3. The overall reaction of fatty acid synthase. * The first condensation reaction is catalysed by β-ketoacyl-ACP synthase III (KAS III), which uses acetyl-CoA and malonyl-ACP substrates. WebThe first protein is designated β-ketoacyl-ACP synthase I and participates in the conversion of acetyl-ACP to palmitoyl-ACP, whereas the second protein is designated β …
