Amino-acid Sequence Visualizer

Amino-acid Sequence Visualizer is an interactive web-based tool designed for rapid exploration, annotation, and export of protein sequences for bioinformatics workflows. Paste or upload FASTA-formatted sequences to render each entry as an individual or aligned layout, interactive grid, enabling intuitive inspection of residue-level details and patterns.

Choose from a range of available color schemes including Clustal, Zappo, Taylor, Rasmol, and a color-blind-friendly palette to visualize amino acid properties such as hydrophobicity, charge, and chemical class, with an adaptive legend that updates in real time. Instantly search for and highlight sequence motifs (supports X/* for variable residues), or select any region to analyze length and hydrophobic content.

The interface supports fast residue mutagenesis via double-click, with undo/redo options for rapid residue swapping. All sequence tracks remain interactive: simply drag-and-drop to reorder, or lock tracks to prevent accidental edits. When ready, export high-resolution SVG or PNG images that fully preserve your chosen color mapping, sequence highlights, mutations, and custom legends that are ready for publication or presentation.
