The Phosphorylation Site Database: A guide to the serine-, threonine-, and/or tyrosine-phosphorylated proteins in prokaryotic organisms.

The Phosphorylation Site Database [http://vigen.biochem.vt.edu/xpd/xpd.htm] provides ready access to information from the primary scientific literature concerning those proteins from prokaryotic organisms, i.e., the members of the domains Archaea and Bacteria, that have been reported to undergo covalent phosphorylation on the hydroxyl side chains of serine, threonine, and/or tyrosine residues. Where known, the sequence of the site(s) of phosphorylation and the functional consequences of phosphorylation also are included. Active links enable users to quickly access further information concerning the phosphoprotein of interest from PubMed, GenBank, SWISS-PROT, and PIR.
