Operated by the SIB Swiss Institute of Bioinformatics, Expasy, the Swiss Bioinformatics Resource Portal, provides access to scientific databases and software tools in different areas of life sciences.
ProtParam [ Documentation / Reference ] is a tool which allows the computation of various physical and chemical parameters for a given protein stored in UniProtKB or for a user entered protein sequence.
Translate tool. Translate is a tool which allows the translation of a nucleotide (DNA/RNA) sequence to a protein sequence.
Compute pI/Mw for UniProtKB entries or one user-entered sequence. Please enter one or several UniProtKB AC/ID (e.g. P04406 or ALBU_HUMAN ), each on a separate line. Alternatively, enter one protein sequence in single letter code. The theoretical pI and Mw will then be computed.
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).
ProtScale allows you to compute and represent the profile produced by any amino acid scale on a selected protein. An amino acid scale is defined by a numerical value assigned to each type of amino acid.
PeptideMass [ Documentation / References ] cleaves a protein sequence from the UniProt Knowledgebase (Swiss-Prot and TrEMBL) or a user-entered protein sequence with a chosen enzyme, and computes the masses of the generated peptides. The tool also returns theoretical isoelectric point and mass values for the protein of interest.
May 29, 2024 · Database of protein domains, families and functional sites. PROSITE consists of documentation entries describing protein domains, families and functional sites as well as associated patterns and profiles to identify them [ More... / References / Commercial users ].
EPD is a collection of eukaryotic promoters derived from published articles. Instead, the EPDnew databases (HT-EPD) are the result of merging EPD promoters with in-house analysis of promoter-specific high-throughput data for selected organisms only. This process gives EPDnew high precision and high coverage .
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 [ ...
