A cytosolic NADP+ dependent malic enzyme has been purified and characterized from an oleaginous yeast Rhodotorula mucilaginosa IIPL32 to investigate its role in lipid biosynthesis. The enzyme has selective and high affinity for NADP and L-malate. Sesamol, a nonoil component of sesame seed oil, has been used during nitrogen depleted condition to evaluate inhibition of malic enzyme and lipid production. Sesamol did not inhibit purified malic enzyme. Sesamol was converted into catechol like metabolite to impart enzyme inhibition and thus lipid production by decreased supply of NADPH+.
