title: Fatty acid synthesis in mitochondria from Saccharomyces cerevisiae.
abstract: The ability of purified mitochondria isolated from S. cerevisiae to synthesize fatty acids and especially very long chain fatty acids (VLCFA) has been investigated. The VLCFA synthesis requires malonyl-CoA as the C2 unit donor and NADPH as the reducing agent. Moreover the yeast mitochondrial elongase is able to accept either exogenous long chain fatty acyl-CoAs as substrates or elongate endogenous substrates. In the latter case, ATP is required for full activity. Besides this important VLCFA formation, the mitochondria from S. cerevisiae were also able to synthesize C16 and C18.
