Biosynthesis of castor oil: effect of polyamines on the acylation of lysophosphatidic acid at the sn-2 position with ricinoleic acid.
نویسندگان
چکیده
Polyamines with diamine structures of chain length longer than 3C were essential for the synthesis of phosphatidic acid (PA) from ricinoleoyl-CoA and lysophosphatidic acid (LPA) by the castor LPA acyltransferase reaction, suggesting that polyamines modulate enzyme affinity for the acyl-CoA substrate in vivo.

Expression of Castor LPAT2 Enhances Ricinoleic Acid Content at the sn-2 Position of Triacylglycerols in Lesquerella Seed
Lesquerella is a potential industrial oilseed crop that makes hydroxy fatty acid (HFA). Unlike castor its seeds are not poisonous but accumulate lesquerolic acid mostly at the sn-1 and sn-3 positions of triacylglycerol (TAG), whereas castor contains ricinoleic acid (18:1OH) at all three positions. To investigate whether lesquerella can be engineered to accumulate HFAs in the sn-2 position, mult...
متن کاملRicinoleic acid biosynthesis and triacylglycerol assembly in microsomal preparations from developing castor-bean (Ricinus communis) endosperm.
Microsomal membrane preparations from the developing endosperm of castor bean (Ricinus communis) catalysed the transfer of oleate from [14C]oleoyl-CoA to phosphatidylcholine (PtdCho). In the presence of NADH, radioactive ricinoleate (12-hydroxyoctadec-9-enoate) was synthesized from [14C]oleate, and this was largely recovered in PtdCho and as free fatty acid. The addition of unlabelled ricinoleo...

Using myoelectric recording techniques, we examined the myoelectric effects of castor oil; ricinoleic acid (cis isomer), the active ingredient of castor oil; and ricinelaidic acid (trans isomer) in the small intestine of New Zealand white rabbits. Ricinoleic acid, 2 microgram/kg per min (6mM), was perfused into a distal 12-cm ileal loop. An abnormal myoelectric pattern developed that was simila...
متن کاملThe Enzymology of Castor Oil Biosynthesis
The castor plant Ricinus communis L., Euphorbiaceae produces seeds containing a unique oil. Castor oil is the only commodity vegetable oil that contains significant amounts of hydroxy fatty acid. This fatty acid is ricinoleic acid (12-hydroxy oleic acid) (Fig. 1) and it comprises up to 90% of the total fatty acid (FA) content of castor oil. Due to the physical and chemical properties imparted b...

A fieldexperiment was conducted in southeastern Sicily with the aim of assessi...
