The Proteolysis MAP (PMAP) was an integrated web resource focused on proteases.[1] Its domain now links to a scam/spam browser extender.

Rationale

PMAP was designed to aid the protease researchers in reasoning about

metabolic pathways
.

History and funding

PMAP was originally created at the

Burnham Institute for Medical Research, La Jolla, California. In 2004 the National Institutes of Health (NIH) selected a team led by Jeffrey W. Smith
, to establish the Center on Proteolytic Pathways (CPP). As part of the NIH Roadmap for Biomedical research, the center develops technology to study the behavior of proteins and to disburse that knowledge to the scientific community at large.

Focal point

Proteases are a class of

blood clotting. Life could not exist without them. Extensive on-line classification system for proteases (also referred as peptidases) is deposited in the MEROPS
database.

Goal

Proteolytic pathways, or proteolysis, are the series of events controlled by proteases that occur in response to specific stimuli. The clotting of blood and production of insulin can be viewed as proteolytic pathways. The activation, regulation and inhibition of the protein are protease reactions to changing glucose levels and trigger other proteases downstream.

Database content

PMAP integrates five databases. ProteaseDB and SubstrateDB, are driven by an automated annotation pipeline that generates dynamic 'Molecule Pages', rich in molecular information. CutDB

metabolic pathways whose function can be dynamically modeled in a rule-based manner. Hypothetical networks are inferred by semi-automated culling from the literature. Protease software tools may help analyze individual proteases and proteome
-wide datasets.

Usage

Popular destinations in PMAP are Protease Molecule Pages and Substrate Molecule Pages. Protease Molecule Pages show recent news in

bioinformatic
databases section. Substrate Molecule Pages display protein domains and experimentally derived protease cut-sites for a given protein target of interest.
