FunctionCELA1_PIG Acts upon elastin. 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 PubMedComplete and highly redundant data sets were collected at nine different wavelengths between 0.80 and 2.65 A on a xenon derivative of porcine pancreatic elastase in both air and helium atmospheres. The magnitude of the anomalous signal, as assessed by the xenon-peak height in the anomalous difference Patterson synthesis, is affected by the wavelength of data collection as well as by the scaling model used. For data collected at wavelengths longer than 1.7 A, the use of a three-dimensional scaling protocol is essential in order to obtain the highest possible anomalous signal. Based on the scaling protocols currently available, the optimal wavelength range for data collection appears to be between 2.1 and 2.4 A.
