The Saccharomyces Genome Database (SGD) provides Internet access to the complete Saccharomyces cerevisiae reference genome DNA sequence, its genes and their products, the phenotypes of its mutants, and the literature supporting these data. The amount of information and the number of features provided by SGD have increased greatly following the release of the S. cerevisiae genomic sequence. SGD aids researchers by providing not only basic information, but also tools such as sequence similarity searching that lead to detailed information about features of the genome and relationships between genes. SGD presents information using a variety of user-friendly, dynamically created graphical displays illustrating physical, genetic and sequence feature maps.
The biocurators at SGD aim to annotate each gene by identifying function(s) from primary literature and linking to terms using the structured knowledge representation in the Gene Ontology. Additionally, functions identified from high throughput experiments as well as computationally predicted function annotations are included from GO Annotation project.
