Cleaved Radioactivity of Phosphopeptides (CRP) performs in silico proteolytic cleavage of protein sequences and reports the radioactivity that would be observed if a given serine, threonine or tyrosine were phosphorylated.
The Human Metabolome Database (HMDB) is a freely available electronic database containing detailed information about small molecule metabolites found in the human body. The database supports extensive text, sequence, chemical structure and relational query searches.
HUPO Proteomics Standards Initiative (PSI) provides data representation standards to facilitate the exchange, comparison and validation of proteomics data.
The University of Minnesota Biocatalysis/Biodegradation Database (UM-BBD) contains information on compounds, enzymes, reactions and microorganism entries. It includes a Biochemical Periodic Table (UM-BPT) and a rule-based Pathway Prediction System (UM-PPS) that predicts plausible pathways for microbial degradation of organic compounds. UM-BBD compound data are contributed to PubChem and ChemSpider, the public chemical databases.
