) that carry out an increasing fraction of routine tasks such as protein production, crystallization and X-ray data collection. Members of the consortium improve their productivity by sending materials to these facilities, receiving the resulting products or data, and reporting this activity to the database. This helps to minimize redundant pursuits of targets. This structural and functional information is publicly available. The five core facilities available to consortium members provide services for cloning, expression, and purification of proteins as well as crystallization and subsequent diffraction and data analysis of protein crystals. Furthermore, a database has been developed to record all activity done within the consortium. This database also tracks the movement of materials between members and allows the up to the minute status to be recorded and available to all other members.
