Vladimir Ivanisenko with Alexey Eroshkin
are pleased to announce the availability of an easy-to-use,
state-of-the-art MS-DOS application designed to solve traditional
and new tasks of protein science.
- includes intuitive user interface to facilitate data analysis;
- inputs single and multiple protein sequences, activity/property/
genotype data, protein 3D structures;
- relates experimental data to protein primary and tertiary structure;
- finds sites influencing protein activity/property;
- finds relationships between protein sites' characteristics
(hydrophobicity, amphipathicity, etc.) and protein activities;
- investigates differences between proteins divided by functional,
evolutionary or other criteria (for example, relates genotype
- investigates physico-chemical factors related with activity changes in
a set of mutant proteins (including multiple physico-chemical factors);
- simulates protein-engineering experiments and predicts activity of
- searches motifs and patterns in combinatorial libraries (peptide and
- provides linear correlation and multiple linear regression
analysis, discriminant, ANOVA and alphabetical analysis;
- classic profile/plot analysis for a single sequence (hydrophobicity,
helical amphipathicity, etc.) suplemented with average, min, max and
dispresion plots for a set of sequences;
- searches regions with high and low variability of physico-chemical
- calculates structure-activity correlation profile;
- performs cross and inter-group variability analysis based on
several matrices of amino acid similarity;
- main part of methods works with sequential and spatial sites;
- maps obtained results onto 3D structure;
- sorts sequences by activity, group number, motifs found;
- visualizes multiple alignments and protein 3D structures (stereo)
with sites highlighted;
- has data converter from several protein sequence formats (FASTA,
SWISS-PROT, CLUSTAL, PIR, IG);
- has data bases with 50 aligned protein families, more than 60 amino
acid properties, HELP, Manual and examples with program applications.
ProAnalyst MAY BE USEFUL:
- for chemists and biochemists making investigations of
protein structure-function and structure-activity analysis;
- for protein engineers trying to improve some protein properties;
- for molecular biologists that need to get sense from multiple protein
alignments and to analyze complicated combinatorial libraries;
- for geneticists studying phenotype-genotype correlations;
- for those who need color protein 3D pictures with sites highlighted;
- for students in any field of PROTEIN SCIENCE;
- for those who interested in comparative protein sequence analysis.

ProAnalyst is available from EBI software library:
(as self-extracted archive).
Current version works with up to 15 sequences. The length of sequences
must be less than or equal to 5000.
