Abstract:
Bovine milk lysozyme has been partially purified by a method developed in this laboratory. We have shown, by preliminary sequential analysis, and by gel filtration on HPLC, that the product is a mixture of two components. One of these, the enzymically active one, differs in its N-terminal sequence from that of "lysozyme 2", a bovine stomach mucosal enzyme, by 7 residues within the first 39 residues. However, some of its properties differ markedly from those of lysozyme 2. The other component, comprising 70% by weight of the total mixture, bears no sequential resemblance to any protein known to us. Our two component system appears to be the same as the preparation of Chandan et al. (Biochim. Biophys. Acta 110, 289 (1965], which they concluded was an homogeneous preparation of lysozyme.
