TL;DR: This work has analyzed the stability of protein mutants using three different data sets of 1791, 1396, and 2204 mutants, respectively, for thermal stability, free energy change due to thermal, and denaturant denaturations, and observed that the classification significantly improved the accuracy of prediction.
Abstract: Prediction of protein stability upon amino acid substitutions is an important problem in molecular biology and it will be helpful for designing stable mutants. In this work, we have analyzed the stability of protein mutants using three different data sets of 1791, 1396, and 2204 mutants, respectively, for thermal stability (ΔTm), free energy change due to thermal (ΔΔG), and denaturant denaturations (ΔΔG), obtained from the ProTherm database. We have classified the mutants into 380 possible substitutions and assigned the stability of each mutant using the information obtained with similar type of mutations. We observed that this assignment could distinguish the stabilizing and destabilizing mutants to an accuracy of 70–80% at different measures of stability. Further, we have classified the mutants based on secondary structure and solvent accessibility (ASA) and observed that the classification significantly improved the accuracy of prediction. The classification of mutants based on helix, strand, and coil distinguished the stabilizing/destabilizing mutants at an average accuracy of 82% and the correlation is 0.56; information about the location of residues at the interior, partially buried, and surface regions of a protein correctly identified the stabilizing/destabilizing residues at an average accuracy of 81% and the correlation is 0.59. The nine subclassifications based on three secondary structures and solvent accessibilities improved the accuracy of assigning stabilizing/destabilizing mutants to an accuracy of 84–89% for the three data sets. Further, the present method is able to predict the free energy change (ΔΔG) upon mutations within a deviation of 0.64 kcal/mol. We suggest that this method could be used for predicting the stability of protein mutants. © 2006 Wiley Periodicals, Inc. Biopolymers 82: 80–92, 2006

Abstract: The article presents the results for enrichment of acid-leachable trace metals (ALTMs) from Ennore Creek in north Chennai, a metropolis on the southeast coast of India. ALTMs Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn and Cd along with sediment texture, OC and CaCO3 were analyzed in surface sediments collected during two different seasons, pre-monsoon (PRM) and post-monsoon (POM) seasons to identify and observe the input of trace metals in the creek from various sources in the city limits. The most prominent feature of the ALTMs is the enrichment of Fe, Cr, Cu, Ni, Pb and Zn in the sediments, which is mainly attributed to the intense industrial activities around Chennai, and to the rapid industrialization policies. The ALTMs also indicate their association with the finer fractions, OC and Fe–Mn oxyhydroxides. The enrichment is very well supported by the correlation, grouping and clustering of ALTMs in statistical analysis. The differential behavior of ALTMs in POM season compared to PRM season is possibly due to the excess level of industrial effluents in the channel feeding Ennore Creek. Comparative results of ALTMs with other estuarine regions also indicate that the study area has been enriched with trace metals during the past two decades. The results of the present study suggest the need for a regular monitoring program which will help to improve the quality of Ennore Creek.
