OPTIMIZER is an on-line PHP application that optimizes the codon usage of a DNA sequence to increase its expression level. Users can introduce their own preference tables to be used in the optimization process or use pre-computed tables from more than 150 prokaryotic species under a strong translational selection. Three methods of optimization are available: the 'one amino acid - one codon' approach, a random approach or an intermediate one. Several options, such as avoiding specific restriction sites and several outputs, are also available. This server can be useful for predicting and optimizing the level expression of a gene in heterologous gene expression. See an example of a DNA sequence from Bacteroides thetaiotaomicron.
