Abstract

Protein sequence analysis underpins research in biophysics, computational biology, and bioinformatics. We introduce BEER, a crossplatform graphical interface that accepts FASTA or Protein Data Bank (PDB) files, or manual sequence entry, and instantly computes a suite of physicochemical metrics, such as amino acid composition, Kyte Doolittle hydrophobicity profiles, net charge versus pH curves with automatic isoelectric point determination, solubility predictions, and key indices such as molecular weight, extinction coefficient, GRAVY (grand average of hydropathicity) score, instability index, and aromaticity. BEER's interactive visualizations, including bar and pie charts, hydropathy plots, residue level bead models, and radar diagrams make it easy to explore physicochemical properties of protein chains. A multichain module also enables direct comparison of complex assemblies. Built in Python with BioPython, PyQt5, and matplotlib, BEER delivers complete analyses of sequences up to 10000 residues in under one second.
