A nonapeptide was determined to have the following amino acid com 
position: (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.
