Databases

  • neXtProt  •  neXtProt is an innovative knowledge platform dedicated to human proteins. This resource contains a wealth of high-quality data on all the human proteins that are produced by the 20'000 protein-coding genes found in the human genome. The content of neXtProt is continuously extended so as to provide many more carefully selected data sets and analysis tools. [less]
  • UniProtKB  •  The UniProt Knowledgebase (UniProtKB) is the central hub for the collection of functional information on proteins with accurate, consistent and rich annotation. It consists of: UniProtKB/Swiss-Prot (manually-annotated records and curator-evaluated computational analysis) and UniProtKB/TrEMBL (computationally analyzed records awaiting manual annotation). [less]
  • UniProtKB/Swiss-Prot  •  UniProtKB/Swiss-Prot is the manually annotated component of UniProtKB. It contains manually-annotated (reviewed) records with information extracted from the literature and curator-evaluated computational analysis. [less]
  • ENZYME  •  ENZYME is a repository of information relative to the nomenclature of enzymes. It is primarily based on the recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (IUBMB) and it describes each type of characterized enzyme for which an EC (Enzyme Commission) number has been provided. [less]
  • GPSDB  •  GPSDB (Gene and Protein Synonym DataBase) collects gene/protein names, in a species specific way, from several biological resources. A web-based search interface gives access to the database: given a gene/protein name, it retrieves all synonyms for this entity and queries Medline with a set of user-selected terms. [less]
  • HAMAP  •  HAMAP is a system for the classification and annotation of protein sequences. It consists of a collection of manually curated family profiles for protein classification, and associated, manually created annotation rules that specify annotations that apply to family members. HAMAP is applied to bacterial, archaeal and eukaryotic proteins and used to annotate records in UniProtKB via UniProt's automatic annotation pipeline. [less]
  • MetaNetX  •  MetaNetX.org allows to access, analyse and manipulate genome-scale metabolic networks as well as biochemical pathways. It consistently integrates data from various public resources and makes the data accessible in a standardized format using a common namespace. Models can be interactively compared, analysed (e.g. detection of dead-end metabolites/reactions, flux balance analysis or simulation of reaction/gene knockouts), manipulated and exported. Users can upload their own metabolic models. [less]
  • UniPathway  •  UniPathway is a curated resource of metabolic pathways for the UniProtKB/Swiss-Prot knowledgebase. [less]

Tools

  • AACompSim  •  Compare amino acid composition of a UniProtKB entry with some or all other UniProtKB entries. Several constellations are available, corresponding to various amino acid analysis techniques. [less]
  • Biochemical Pathways  •  Digitized version of the Roche Applied Science "Biochemical Pathways" wall chart. The map, linked to relevant ENZYME database entries, can be browsed online, and keyword searches are available. [less]
  • Compute pI/MW  •  Compute the theoretical pI (isoelectric point) and Mw (molecular weight) for a list of UniProt Knowledgebase (Swiss-Prot or TrEMBL) entries or for user entered sequences [less]
  • FindMod  •  Predict potential protein post-translational modifications (PTM) and find potential single amino acid substitutions in peptides. The experimentally measured peptide masses are compared with the theoretical peptides calculated from a specified Swiss-Prot/TrEMBL entry or from a user-entered sequence, and mass differences are used to better characterise the protein of interest. [less]
  • FindPept  •  Identify peptides that result from unspecific cleavage of proteins from their experimental masses, taking into account artefactual chemical modifications, post-translational modifications (PTM) and protease autolytic cleavage. [less]
  • GPMAW lite  •  GPMAW lite is a protein bioinformatics tool to perform basic bioinformatics calculations on any protein amino acid sequence, including predicted molecular weight, molar absorbance and extinction coefficient, isoelectric point and hydrophobicity index, as well as amino acid composition and protease digest. [less]
  • HAMAP  •  HAMAP is a system for the classification and annotation of protein sequences. It consists of a collection of manually curated family profiles for protein classification, and associated, manually created annotation rules that specify annotations that apply to family members. HAMAP is applied to bacterial, archaeal and eukaryotic proteins and used to annotate records in UniProtKB via UniProt's automatic annotation pipeline. [less]

Users can upload their own metabolic models. [less]
  • PeptideCutter  •  PeptideCutter predicts potential substrate cleavage sites, cleaved by proteases or chemicals in a given protein sequence. The tool returns the query sequence with the possible cleavage sites mapped on it and/or a table of cleavage site positions. [less]
  • PoPS  •  The PoPS project is a set of computational tools for investigating protease specificity. The main PoPS program allows users to model and profile protease specificity and predict substrate cleavage. Other tools are available to search for substrates within proteomes (protein databases for organisms), and create simple matrix models of specificity from experimental data. [less]
  • PredictProtein  •  PredictProtein integrates feature prediction for secondary structure, solvent accessibility, transmembrane helices, globular regions, coiled-coil regions, structural switch regions, B-values, disorder regions, intra-residue contacts, protein-protein and protein-DNA binding sites, sub-cellular localization, domain boundaries, beta-barrels, cysteine bonds, metal binding sites and disulphide bridges. [less]
  • PROPSEARCH  •  PROPSEARCH was designed to detect functional and / or structural homologs, if the sequence identity is below about 25%. It uses the amino acid physico-chemical properties, content of bulky residues, content of small residues, average hydrophobicity, average charge a.s.o. and are used as query vector. Sequences in the database are transformed into vectors as well, and the euclidian distance between the query and database sequences is calculated. [less]
  • ProtParam  •  Compute various physical and chemical parameters for a given protein sequence. The computed parameters include the molecular weight, theoretical pI (isoelectric point), amino acid composition, atomic composition, extinction coefficient, estimated half-life, instability index, aliphatic index and grand average of hydropathicity (GRAVY). [less]
  • ProtScale  •  Compute and represent the profile produced by any amino acid scale on a selected protein sequence. The most frequently used scales are the hydrophobicity or hydrophilicity scales and the secondary structure conformational parameters scales, but ProtScale provides more than 50 predefined scales entered from the literature. [less]

  • TargetP  •  TargetP 1.1 predicts the subcellular location of eukaryotic proteins. The location assignment is based on the predicted presence of any of the N-terminal presequences: chloroplast transit peptide (cTP), mitochondrial targeting peptide (mTP) or secretory pathway signal peptide (SP).  [less]
