Correlating dynamic amino acid properties with success rate of crystallization of proteins from Bacteroides vulgatus

Abstract

AbstractTo enhance the success rate of protein crystallization, many studies were conducted to determine the relationship between amino acid properties and the success rate of protein crystallization. Although those were successful, new efforts should be made to search for the new factors, which affect protein crystallization. In this study, two dynamic amino acid properties were used to correlate with the success rate of crystallization of proteins from Bacteroides vulgatus, because the amino acid properties used in previous studies were steady. As previously done, logistic regression and neural network were used to model that relationship, and the results were compared against those obtained from each of 532 amino acid properties, which severed as benchmark. The results demonstrated that dynamic amino acid properties should be taken into consideration of protein crystallization. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
