GPMAW Lite is a free, online protein analysis tool by Alphalyse that will certainly be of use to a number of researchers and students alike. To begin, users either enter the NCBI/UNIPROT accession number to search for the protein of interest, or simply copy and paste the amino acid sequence directly into the query field. Next, users select the analyses they wish to conduct. They may choose to display general information about the protein (such as molecular weight and isoelectric point), an amino acid composition table, or a table of predicted peptides resulting from complete digestion of the protein with specific proteases. In addition, the tool allows users to colorize the protein sequence according to amino acid type. Help buttons throughout the page explain specific features or results to users, and the analysis results are formatted to print.
