Fatty acid synthetase
The activity of the enzyme is controlled in several ways. The essential lysine residue in the active site plays an important role in regulation of activity. The lysine molecule can be deacetylated by another class of enzyme called sirtuins. In mammals, the cytoplasmic-nuclear synthetase (AceCS1) is activated by SIRT1 while the mitochondrial synthetase (AceCS2) is activated by SIRT3. This action increases activity of this enzyme. The exact location of the lysine residue varies be… WebJan 26, 2024 · Our results suggest that MoPcs60 is a key peroxisomal-CoA synthetase involved in fatty acid β-oxidation and pathogenicity in rice blast fungi. Fatty acid metabolism is important for the maintenance of fatty acid homeostasis. Free fatty acids, which are toxic in excess, are activated by esterification with coenzyme A (CoA), then …
