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 کاملCharacterization of cDNAs encoding small GTP-binding proteins from maize.
To date, more than 100 genes encoding small GTP-binding proteins (21-25 kD) have been identified from various eukaryotic organisms, including mammals, insects, yeasts, and higher plants (Hall, 1990; Bourne et al., 1991; Terryn et al., 1993). These proteins, which contain highly homologous regions that have been conserved during evolution, are conveniently classified into three major groups; ras...
متن کاملRegulation of triacylglycerol biosynthesis in embryos and microsomal preparations from the developing seeds of Cuphea lanceolata.
Embryos of Cuphea lanceolata have more than 80 mol% of decanoic acid ('capric acid') in their triacylglycerols, while this fatty acid is virtually absent in phosphatidylcholine (PtdCho). Seed development was complete 25-27 days after pollination, with rapid triacylglycerol deposition occurring between 9 and 24 days. PtdCho amounts increased until day 15 after pollination. Analysis of embryo lip...
متن کاملCloning of a cDNA encoding 3-ketoacyl-acyl carrier protein synthase III from Arabidopsis.
The initial step of fatty acid biosynthesis in both plants and Escherichia coli is the condensation of malonyl-acyl carrier protein with acetyl-COA, a reaction that is catalyzed by KAS 111 (Jackowski and Rock, 1987; Jackowski et al., 1989; Jaworski et al., 1989; Clough et al., 1992). In E. coli, KAS 111 has been implicated as a site of regulation for de novo fatty acid synthesis (Jackowski and ...
متن کاملNucleotide Sequence of a Complementary DNA Clone Encoding Stearoyl-Acyl Carrier Protein Desaturase from Simmondsia chinensis.
Stearoyl-ACP' desaturase (EC 1.14.99.6) converts stearoyl[ 18:0]-ACP to oleoyl[ 18:1(9)]-ACP in the unsaturated fatty acid synthesis of plants and plays a role in the regulation of fatty acid composition of plant membranes and seed oils (1). Several cDNA clones ofmRNAs encoding plant stearoylACP desaturase have now been described (2-4). The coding sequences for the mature enzyme are highly homo...
