1. To determine the sequence of amino acids in protein, partial hydrolyses at different points are made and then compared to other sets of partial hydrolyses For example: Complete hydrolysis gave: Phenylalanine-1 Histidine-2 Glutamic acid-1 Leucine - 4 Asparagine-1 Cystine -2 Glutamine-1 Glycine - 2 The Partial Hydrolyses yielded the following: 1st Hydrolysis : 4 polypeptides ● . IA: phe-val-asn-gln-his-leu IB: IC: leu-tyr-leu-val ID: val-cys-gly 2nd Hydrolysis: 3 polypeptides IIA: phe-val-asn-gIn-his-leu-cys-gly-ser-his-leu IIB: val-glu-ala-leu-tyr-leu IIC: val-cys-gly Write down the primary structure of this polypeptide by finding the overlaps of the amino acids therein: Serine-1 Valine-3 Alanine-1 tyrosine-1 cys-gly-ser-his-leu-val-glu-ala
