After trypsin cleavage of the heptapeptide from protein X, the peptlde's compOsition and sequence was determined. The fOllowing were the results of the sequenclng process: 1. When the peptide was treated with dinitrofluorobenzene (DNFB), DNP-asp and a mixture of amino acids were produced. 2. When the same Intact peptide was treated with streptococcal protease, a pentapeptide of composition asp, asN, cys, gly and ser and 2 amlno acids were released. 3. When the heptapeptlde was also treated with hydrOxylamine HCI, a tripeptide and a tetrapeptide were obtained.
