Abstract
The amino acid sequence of a lysozyme, (B-enzyme), from Bacillus subtilis YT-25 was determined by conventional methods. B-Enzyme comprised 117 amino acid residues and had a heterogeneous sequence in the amino-terminal region. The amino acid sequence of B-enzyme was different from those of all other lysozymes the sequences of which are known. However, the partial amino acid sequence of Ser(74) to Ser(97) of B-enzyme was homologous with that of the active-site region of hen egg-white lysozyme (Ser(36) to Ser(60], which includes one of the catalytic amino acids, Asp(52). It is interesting that B-enzyme has an amino acid sequence homologous with that of the gag protein p25 of the AIDS virus ARV-2.Entities:
