Black PN, Zhang Q, Weimar JD, Di Russo CC (1997): Mutational analysis of a fatty Acyl-coenzyme A Synthetase signature motif identifies seven amino acid residues that modulate fatty acid substrate specificity. Key words: cellular genetic algorithm, dynamic optimization, density dependence scheme Reference  R. The activation of fatty acids by Acyl-Co A Synthetase is the need of de novo lipid biosynthesis, fatty acid catabolism and remodeling of biological membranes. The computation results indicate that new algorithms demonstrate their superiority respectively on both convergence and diversity.
