ESTHER Database

The server ESTHER (ESTerases and alpha/beta-Hydrolase Enzymes and Relatives) is dedicated to the analysis of proteins or protein domains belonging to the superfamily of alpha/beta-hydrolases, exemplified by the cholinesterases.

Structure of YqiA, Klebsiella pneumoniae serine hydrolase, unbound is available (9BI7) and will be published soon by Randall, G.T. and Fellner, M. PME-1 S156A and M335D knock-in mice deficient in methylesterase and PP2A inhibitory activity, respectively showed phenotypes distinct from the perinatal lethality of PME-1 null mice. The loss of methylesterase activity due to the S156A mutation resulted in systemic apoptosis characterized by brain atrophy: the layers of the cerebellum collapsed with fewer Purkinje cells and more microglia. M335D mutant pups did not appear deformed and had intact brains but died about two days after birth with a demonstrated loss of olfaction and apoptosis in the olfactory epithelium (Ikeda et al. ) A novel butyrylcholinesterase inhibitor induces antidepressant, pro-cognitive, and anti-anhedonic effects in Flinders Sensitive Line rats: The role of the ghrelin-dopamine cascade as published by Olivier et al.
