Abstract: With the complete sequencing of multiple genomes, there have been
extensions in the methods of sequence analysis from single gene/protein-based
to analyzing multiple genes and proteins simultaneously. Therefore, there is a
demand for user-friendly software tools that will allow mining of these
enormous datasets. PPD is a WWW-based database for comparative analysis of
protein lengths in completely sequenced prokaryotic and eukaryotic genomes.
PPD's core objective is to create protein classification tables based on the
lengths of proteins by specifying a set of organisms and parameters. The
interface can also generate information on changes in proteins of specific
length distributions. This feature is of importance when the user's interest is
focused on some evolutionarily related organisms or on organisms with similar
or related tissue specificity or life-style. PPD is available at: PPD Home.
