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. The computed parameters include the molecular weight, theoretical pI, amino acid composition, atomic composition, extinction coefficient ...
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.
SIM is a program which finds a user-defined number of best non-intersecting alignments between two protein sequences or within a sequence [more]. Once the alignment is computed, you can view it using LALNVIEW, a graphical viewer program for pairwise alignments [reference to LANVIEW].
Protein characterization tools in the context of PMF experiments include FindMod, to predict posttranslational modifications and single-amino acid substitutions; GlycoMod, a tool to predict the possible compositions for glycan structures, or compo-
RandSeq is a tool which generates a random protein sequence. Please fill out this form to submit the parameters for the generation of a random sequence. Size of the sequence (20 to 9999 amino acids): Composition of the sequence: Equal composition for all amino acids. Composition of a specific sequence - please enter a UniProtKB ID or AC:
Personalized information retrieval from the literature. 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.
Because most protein sequences are derived from translation of nucleotide sequences and are mere predictions, the PE line indicates what the evidences are of the existence of a protein. Note that the 'PE' line does not give information on the accuracy or correctness of the sequence displayed.
PeptideMass. 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.
