Correction: Role of Key Salt Bridges in Thermostability of G. thermodenitrificans EstGtA2: Distinctive Patterns within the New Bacterial Lipolytic Enzyme Family XV

After communicating with the corresponding authors of “ESTHER, the database of the α/βhydrolase fold superfamily of proteins: tools to explore diversity of functions” [2], published in Nucleic Acids Research, the authors request to change the assignment of a new “family XV” described in our paper to an assignment of a new “subfamily XIII.2”. At the time of publication, “family XV” had already been proposed as an extension of the original classification of Arpigny and Jaeger for a different family of enzymes by Lenfant, et al, in 2012. We would not have used the name “family XV” if we had been aware of the other study before publishing our work. Based on extensive phylogenetic analyses, and structural and functional criteria, it is more appropriate to subdivide the family XIII. Every instance of “family XV” in the paper should be replaced by “subfamily XIII.2” The correct title should be: Role of Key Salt Bridges in Thermostability of G. thermodenitrificans EstGtA2: Distinctive Patterns within the New Bacterial Lipolytic Enzyme Subfamily XIII.2. The correct citation should be: Charbonneau DM, Beauregard M (2013) Role of Key Salt Bridges in Thermostability of G. thermodenitrificans EstGtA2: Distinctive Patterns within the New Bacterial Lipolytic Enzyme Subfamily XIII.2. PLoS ONE 8(10): e76675. doi:10.1371/ journal.pone.0076675 We also provide a revised Fig 5 and S8 Fig incorporating the new nomenclature. The criteria for the separation and assignation of protein sequences to the new subfamily XIII.2 are the same as the criteria described for the separation of the initially proposed family XV. The criteria proposed for the subdivision N’ are maintained identical to the initial proposition. Criteria for the assignation of lipolytic enzymes to the family XIII.2:
