Anonapeptide was determined to have the following amino acid composition: (lys)2, (gly) 2, (phe) 2, his, leu, met. the native peptide was incubated with 1-fluoro-2,4-dinitrobenzene (fdnb) and then hydrolyzed; 2,4-dinitrophenylhistidine was identified by hplc. when the native peptide was exposed to cyanogen bromide (cnbr), an octapeptide and free glycine were recovered. incubation of the native peptide with trypsin gave a pentapeptide, a tripeptide, and free lys. 2,4-dinitrophenyl-histidine was recovered from the pentapeptide, and 2,4- was recovered from the tripeptide. digestion with the enzyme pepsin produced a dipeptide, a tripeptide, and a tetrapeptide. the tetrapeptide was composed of (lys) 2, phe, and gly. the native sequence was determined to be:
