153L, 154L - PubMed Abstract: 
The structure of goose egg-white lysozyme (GEWL) has been refined to an R-value of 15.9% at 1.6 A resolution. Details of the structure determination, the refinement and the structure itself are presented. The structure of a complex of the enzyme with the trisaccharide of N-acetyl glucosamine has also been determined and refined at 1 ...
