ACHE — Capsicum annuum

Summary

T459_27774 (ACHE) in pepper (Capsicum annuum) chromosome 11 encodes a GDSL esterase/lipase belonging to the SGNH hydrolase superfamily. The enzyme exhibits sinapine esterase, acetylajmaline esterase, carboxylic ester hydrolase, glycosidase, acyltransferase, and lipase activities, along with serine O-acyltransferase activity and IgE binding. This gene is associated with acetylcholine breakdown, memory, endoplasmic reticulum organisation, isoprenoid anabolism, lipolysis, detoxification, lipid and alkaloid metabolism, nodulation, response to wounding, and defense response. It localises to the symbiosome and extracellular space. The gene has been connected to pungency. Studies of related genes in other species link the family to EC 3.1.1.49 and EC 3.1.1.80 activities, though these are not established for this pepper gene.
