inhibits the overall reaction and beta-ketoacyl reductase reaction of FAS with IC50 values of 4.61 microg/ml and 20.3 microg/ml, respectively. Inhibits the overall reaction of FAS competitively with acetyl-CoA, noncompetitively with malonyl-CoA and in a mixed manner with NADPH
-

-
FabG is fully unfolded at 4 M, approximately 90% of the enzyme activity can be recovered on dialyzing the denaturant. In presence of NADPH, there is no stabilization of FabG in case of equilibrium unfolding with guanidinium chloride

inhibits the overall reaction and beta-ketoacyl reductase reaction of FAS with IC50 values of 11.1 microg/ml and 21.9 microg/ml, respectively. In 3 T3-L1 preadipocytes, resveratrol reduces lipid accumulation remarkably
RNAi
-
suppresses KCR activity, which results in a reduction of cuticular wax load and affects very-long-chain fatty acid composition of sphingolipids, seed triacylglycerols, and root glycerolipids. RNAi-suppressed Arabidopsis KCR1 plants display fused vegetative and reproductive organs, an abnormal root morphology and have abnormal trichome and epidermal cell morphology

FabG is fully unfolded at 6 M, approximately 90% of the enzyme activity can be recovered on dialyzing the denaturant. Two states in the reversible unfolding process of FabG in presence of NADPH, one is an activity-enhanced state and the other, an inactive state in case of equilibrium unfolding with urea
