title: The Synthetic Gene Designer: a flexible web platform to explore sequence manipulation for heterologous expression.
abstract: "Codon optimization" is a general approach to improving heterologous expression where genes are moved from their native genomes into alternatives that exhibit different patterns of codon usage. However, despite reports of successful manipulations and the existence of stand-alone codon optimization software packages or commercial services that offer to redesign genes, the scientific community lacks any systematic understanding of what exactly it means to optimize codon usage. Thus we present a bona fide web application, the "Synthetic Gene Designer," which contrasts with existing software by providing a centralized, free, and transparent platform for the broader scientific community to develop knowledge about synthetic gene design. Consistent with this goal, our software is associated with a moderated e-forum that promotes discussion of synthetic gene design and offers technical support. In addition, the Synthetic Gene Designer presents enhanced functionality over existing software options: for example, it enables users to work with non-standard genetic codes, with user-defined patterns of codon usage and an expanded range of methods for codon optimization. The Synthetic Gene Designer, together with on-line tutorials and the forum, is available at .
