Expression and purification of four different rhizobial acyl carrier proteins.
In rhizobia, besides the constitutive acyl carrier protein (AcpP) involved in the biosynthesis and transfer of common fatty acids, there are at least three specialized acyl carrier proteins (ACPs): (1) the flavonoid-inducible nodulation protein NodF; (2) the RkpF protein, which is required for the biosynthesis of rhizobial capsular polysaccharides; and (3) AcpXL, which transfers 27-hydroxyoctac...
متن کاملGenes of ACYL CARRIER PROTEIN Family Show Different Expression Profiles and Overexpression of ACYL CARRIER PROTEIN 5 Modulates Fatty Acid Composition and Enhances Salt Stress Tolerance in Arabidopsis
Acyl carrier proteins (ACPs) are a group of small acidic proteins functioning as important cofactors in the de novo synthesis of fatty acids. In Arabidopsis, ACPs are encoded by a small gene family comprising five plastid members, AtACP1 to AtACP5, and three mitochondrial members. The biological functions and the transcriptional responses to abiotic stresses of most AtACPs have yet to be elucid...
متن کاملSpinach acyl-carrier proteins: structure, regulation, and progress towards cloning.
specificity is determined by the condensing enzyme, namely 8-ketoacyl-[acyl-carrier-proteinlsynthase 11. For the barley complex they are CoA derivatives which give rise to the C,,, C,, and C,, 3-oxoacyl key intermediates. One can speculate that the condensing enzyme activity specified by the cer-cqu-determined polypeptide is responsible for the noted substrate specificity. Therefore, should one...
متن کاملVersatility of acyl-acyl carrier protein synthetases.
The acyl carrier protein (ACP) requires posttranslational modification with a 4'-phosphopantetheine arm for activity, and this thiol-terminated modification carries cargo between enzymes in ACP-dependent metabolic pathways. We show that acyl-ACP synthetases (AasSs) from different organisms are able to load even, odd, and unnatural fatty acids onto E. coli ACP in vitro. Vibrio harveyi AasS not o...
متن کاملFat Metabolism in Higher Plants: LXII. Stearl-acyl Carrier Protein Desaturase from Spinach Chloroplasts.
Stearyl-acyl carrier protein desaturase (EC 1.14.99.6), present in the stroma fraction of spinach (Spinacia oleracea) chloroplasts, rapidly desaturated enzymatically prepared stearyl-acyl carrier protein to oleic acid. No other substrates were desaturated. In addition to stearyl-acyl carrier protein, reduced ferredoxin was an essential component of the system. The electron donor systems were ei...
