COILS is a program that compares a sequence to a database of known parallel two-stranded coiled-coils and derives a similarity score. By comparing this score to the distribution of scores in globular and coiled-coil proteins, the program then calculates the probability that the sequence will adopt a coiled-coil conformation.

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

HeliQuest calculates from the amino acid sequence of a helix (??-helix, 3-10 helix, 3-11 helix or ?? helix) its physicochemical properties and amino acid composition and uses the results to screen any databank in order to identify protein segments possessing similar features.

Isotopident can estimate the theoretical isotopic distribution of a peptide or protein, a polynucleotide and a chemical compound from its composition (sequence of amino acids expressed in either 1-letter code, sequence of amino acids expressed in 3-letter code, sequence of nucleotides or its chemical formula). Isotopident can also compute its monoisotopic mass. and predict the most likely isotope combination and the exact mass of the given input.

Cleave a protein sequence with a chosen enzyme/protease, and computes the masses of the generated peptides. The tool also returns theoretical isoelectric point and mass values for the protein of interest. If desired, PeptideMass can return the mass of peptides known to carry post-translational modifications, and can highlight peptides whose masses may be affected by database conflicts, polymorphisms or splice variants.

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.

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.

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).

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.

SAPS (Statistical Analysis of Protein Sequences) evaluates a wide variety of protein sequence properties using statistics. Properties considered include compositional biases, clusters and runs of charge and other amino acid types, different kinds and extents of repetitive structures, locally periodic motifs, and anomalous spacings between identical residue types.

Identify proteins with isoelectric point (pI), molecular weight (Mw) and sequence tag, or generate a list of proteins close to a given pI and Mw.

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).

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.
