The crystallographic structure of the digestive lysozyme 1 from Musca domestica at 1.90 Ang.
Structural highlights
FunctionLYS1_MUSDO May not function as a self-defense protein, but as a digestive enzyme, probably in the gut of the insect body. Inactive towards Micrococcus luteus. Active toward glycol chitin. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedLysozymes are mostly known for their defensive role against bacteria, but in several animals lysozymes have a digestive function. Here, the initial crystallographic characterization of two digestive lysozymes from Musca domestica are presented. The proteins were crystallized using the sitting-drop vapour-diffusion method in the presence of ammonium sulfate or PEG/2-propanol as the precipitant. X-ray diffraction data were collected to a maximum resolution of 1.9 angstroms using synchrotron radiation. The lysozyme 1 and 2 crystals belong to the monoclinic space group P2(1) (unit-cell parameters a = 36.52, b = 79.44, c = 45.20 angstroms, beta = 102.97 degrees) and the orthorhombic space group P2(1)2(1)2 (unit-cell parameters a = 73.90, b = 96.40, c = 33.27 angstroms), respectively. The crystal structures were solved by molecular replacement and structure refinement is in progress.
