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.

In these times of international uncertainty and uncomfortable situation due to Covid-19, the ESTHER team wishes each and all of you all the best. Please take care of you, yours, and all others around..

NEW Great news: Maria Laura Bolognesi, Doriano Lamba and Manuela Bartolini announce that the 14th International Meeting on Cholinesterases and 8th Conference of Paraoxonases will take place in-person from 18th to 21th September 2022 in the beautiful city of Bologna, Italy (14che8pon)

NEW The XVII International Symposium on Cholinergic Mechanisms (ISCM-2022) took place during May 8-12, 2022 in Dubrovnik, Croatia. (ISCM-2022)

  • July 13, 2022:
    Huang et al. publish that biochemical and structural data demonstrate that EDS1-PAD4 is a receptor complex for pRib-AMP/ADP, which allosterically promote EDS1-PAD4 interaction with ADR1-L1 but not NRG1A.pRib-AMP/ADP is a missing link in TIR signaling via EDS1-PAD4 and as likely second messengers for plant immunity. Structures are available (7XDD, 7XEY)
