Fig 2: Sample output from the Compute pI / MW tool, where the program was requested to calculate the theoretical pI and MW for the Swiss-Prot entry LACB_BOVIN (P02754). Note that the Compute pI / MW tool shows the sequence of the region of the protein that is under consideration. In this case, the sequence of the mature beta-lactoglobulin is shown, which results when the secretion signal sequence is removed from the precursor polypeptide.
