Abstract:
In order to elucidate the biosynthesis of longchain polyunsaturated fatty acids (PUFAs) in plants we searched for a cDNA encoding a Δ6-specific PUFA elongase from Physcomitrella patens which is known to contain high proportions of arachidonic acid (20:4 Δ5,8,11,14). An EST clone from P. patens was identified by its low homology to the yeast gene ELO1, which is required for the elongation of medium-chain fatty acids. We functionally characterized this cDNA by heterologous expression in Saccharomyces cerevisiae grown in the presence of several fatty acids. Analysis of the fatty acid profile of t

Abstract:
Microsomal fractions from rat small intestine contain a fatty-acid chain-elongation activity. Cofactor requirements are similar to those of the liver microsomal system, but substrate specificity is different. The polyunsaturated arachidonic and timnodonic acids were elongated at very low rates. These results suggest that the relative contents of specific chain-elongation enzymes are different in liver and small intestine.

Abstract It has been found that various thiocarbamate herbicides, known to alter surface wax and cutin synthesis, inhibit the elongation of fatty acids. We have proposed this as a mode of ac­tion of such compounds. Because it is believed that the sulphoxide metabolites of thiocarba­mates are the active intermediates, we have examined the action of 1-aminobenzotriazole (an inhibitor of sulphoxide formation) on the inhibition of very long-chain fatty acid biosynthesis. In all tissues tested, aminobenzotriazole was able to block the specific inhibitory effect of thio­carbamates on fatty acid elon

ABSTRACT The TSC13/YDL015c gene was identified in a screen for suppressors of the calcium sensitivity of csg2Δ mutants that are defective in sphingolipid synthesis. The fatty acid moiety of sphingolipids in Saccharomyces cerevisiae is a very long chain fatty acid (VLCFA) that is synthesized by a microsomal enzyme system that lengthens the palmitate produced by cytosolic fatty acid synthase by two carbon units in each cycle of elongation. TheTSC13 gene encodes a protein required for elongation, possibly the enoyl reductase that catalyzes the last step in each cycle of elongation. The tsc13 muta

Abstract Very long chain fatty acids (VLCFA) are essential molecules that take part in many different cellular processes such as membrane pore stabilization, membrane trafficking and signaling pathways. The fatty acid elongation pathway in yeast has been studied for about a decade. As part of our work on cellular VLCFA elongation, we identified and characterized the condensing enzyme as well as ketoacyl reductases of the elongation pathway in cotton. In order to identify the yeast 3-hydroxyacyl-CoA dehydratase, we introduced a redundancy in this function by engineering a chimera consisting

Abstract:
Very-long-chain fatty acids (VLCFAs) are essential molecules produced by all plant cells, and are precursors of diverse primary and specialized metabolites. VLCFAs are elongated by a fatty acid elongation (FAE) complex of four core enzymes located on the endoplasmic reticulum, which sequentially adds two carbon units to a growing acyl-CoA chain. Identification and characterization of FAE enzymes in Arabidopsis thaliana has revealed that three of the four enzymes act as generalists, contributing to all metabolic pathways that require VLCFAs.

Abstract:
abstract: Trichloroethene (TCE) is a ubiquitous soil and groundwater contaminant. The most common bioremediation approach for TCE relies on the process of reductive dechlorination by Dehalococcoides mccartyi. D. mccartyi use TCE, dichloroethene, and vinyl chloride as electron acceptors and hydrogen as an electron donor. At contaminated sites, reductive dechlorination is typically promoted by adding a fermentable substrate, which is broken down to short chain fatty acids, simple alcohols, and hydrogen. This study explored microbial chain elongation (MCE), instead of fermentation, to promote TCE

Condensing enzymes for very long chain fatty acid (VLCFA) synthesis catalyze the first of a series of four reactions that elongate the growing acyl chain by two carbons at a time.

My research project focused on the characterization of KCS2, a new putative condensing enzyme of Arabidopsis thaliana.
