No other database than ESTHER holds all alpha/beta hydrolase fold proteins together: Interpro, Prosite, Pfam, have multiple entries for subsets of this structural superfamily. A table Synthese shows the correspondance between these database entries and the subfamilies in ESTHER. The ESTHER Table is now a little to big to be usefull. Each file contains one of the 31219 non redundant proteins/genes. The tables grouped in the family table, the syntheses table or the structure table may be more usefull. The Gene_locus nomenclature for these non-redundant entries is a name with 5 characters for the organisms (3 for genera, 2 for the species, except when a common 5 character name exists. ex: ratno is for Rattus norvegicus and human for man. This allows us to keep close to the Swiss-Prot nomenclature). The last characters define the protein, ex: human-acche represents human acetylcholinesterase. ... [Information of the supplier]
