Yeast Biochemical Pathways are created using the Pathway tools software developed by Peter Karp and his colleagues at SRI International. The current datasets of pathways at SGD were generated using the Pathway Tool's PathoLogic module, which generates an initial set of pathways by comparing SGD annotations to a reference database (MetaCyc). Although PathoLogic creates a genome database, this feature is not curated by SGD.

These automatically generated pathways are then manually curated and corrected, based on published S.cerevisiae literature. When necessary, yeast-specific biochemical pathways are added. Since the functions of many of the yeast genes are not yet known, many of the pathways could be incomplete or may even contain errors. Manual curation of pathways is an ongoing process at SGD and we welcome feedback from the research community. If you notice any problems or errors, please send a message to SGD curators.

NOTE:
Pathway tools uses a non-standard port (:8555). If you are working behind a firewall, you will not be able to access these pathways at SGD. If this is the case, request your network administrator to open the :8555 port on the firewall.
