Abstract
This article introduces DoBISCUIT (Database of BIoSynthesis clusters CUrated and InTegrated, http://www.bio.nite.go.jp/pks/), a literature-based, manually curated database of gene clusters for secondary metabolite biosynthesis. Bacterial secondary metabolites often show pharmacologically important activities and can serve as lead compounds and/or candidates for drug development. Biosynthesis of each secondary metabolite is catalyzed by a number of enzymes, usually encoded by a gene cluster. Although many scientific papers describe such gene clusters, the gene information is not always described in a comprehensive manner and the related information is rarely integrated. DoBISCUIT integrates the latest literature information and provides standardized gene/module/domain descriptions related to the gene clusters.
