The Amino Acid Sequence of Copper Pheasant Lysozyme

Abstract

The amino acid sequence of copper pheasant lysozyme was analyzed. Carboxymethylated lysozyme was digested with trypsin and the resulting peptides were sequenced. The established amino acid sequence had three amino acid substitutions at positions 20, 77, and 113 for Lady Amherst's pheasant lysozyme and seven amino acid substitutions at positions 3, 15, 20, 41, 113, 121, and 124 for hen lysozyme. Phenylalanine at position 20 was newly detected in avian lysozyme.
