A clean representation of protein primary sequence can do wonders for making a compelling case about protein fold or function. The Charges tool allows you to annotate custom residue combinations with user-specified colors. The output is a scalable vector graphic file that can be used to make high-quality figures from any protein fasta input.
Preset color combos allow quick and consistent re-use. A favorite preset (Positives Blue, Negatives Red) highlights charged residues.

Originally written by Helena Rasche, the Charges tool has had multiple updates with new preset color combos. Feel free to request a new preset for your research needs!
Charges can be found under CPT: Genomic Overview. Please email the support team if you have any questions!
