RESUMEN
The QUEST Protein Database Center is now making available two Saccharomyces cerevisiae protein databases via the Internet. The yeast electrophoretic protein database (YEPD) is a database of approximately one hundred protein identifications on two-dimensional gels. The yeast protein database (YPD) is a database of gene names and properties of over 3500 yeast proteins of known sequence. These databases can be accessed via a World-Wide Web (WWW) server (URL http:@siva.cshl.org). YPD is available via public ftp (isis.cshl.org) as well, in a spreadsheet format, and in ASCII format. When accessed via WWW, both of these databases have hypertext links to other biological data, such as the SWISS-PROT protein sequence database and the Saccharomyces Genome Database (SacchDB), and to each other.

Until recently, the REF52 2-D gel database of experiments with rat cell lines was accessible only with special software. This database has now been made available to all investigators with access to the Internet, using the World Wide Web (WWW) technology. The package which delivers the database through the WWW has been named the Global Gel Navigator and can be used to explore the data by several methods, including the direct selection of proteins in the displayed gel using the mouse.

The Quest II system is a new two-dimensional (2D) gel analysis software system for the construction and analysis of 2D gel protein databases. A new architectural approach to 2D gel software systems has been utilized. This architecture is based on a tightly coupled client/server model. There are three layers to the system architecture: (i) a database layer consisting of three database servers, (ii) a compute layer consisting of three compute servers and (iii) an extensible user interface layer currently consisting of user interface tools for linearization and merging of scanned images, the segmentation and detection of protein spots on the images, matching, editing, and analysis of gels. The ability to store and retrieve the large volume of spot data inherent in 2D gel analysis while utilizing database technology is demonstrated.
