Parameters :protein_sequence: A ``Bio.Seq`` or string object containing a protein IsoelectricPoint ( protein_sequence, aa_content = None ) ¶Ī class for calculating the IEP or charge at given pH of a protein. I designed the algorithm according to a note by David L. peptide sequences are obtained by calculating the mass differences. Reference points for comparisons of two - dimensional maps of proteins from different human cell types defined in a pH scale where isoelectric points correlate with polypeptide compositions. e.g., peptide sequence, physicochemical properties (length, isoelectric point). The pKa values of the side chains of the twenty common amino acids that comprise most proteins vary from approximately pH 2.8 to pH 11.2 (). The focusing positions of polypeptides in immobilized pH gradients can be predicted from their amino acid sequences.
