ACHE — Asparagus officinalis

Summary

A4U43_C09F4150 (ACHE) on asparagus chromosome 9 encodes an uncharacterized protein belonging to the GDSL and SGNH_hydro_sf families. The gene is annotated with sinapine esterase, acetylajmaline esterase, and carboxylic ester hydrolase activities, as well as glycosidase and esterase activities, and IgE binding. It is associated with acetylcholine breakdown, lipolysis, alkaloid metabolism, nodulation, and defense response. The gene is also associated with cognition and memory, and localizes to the symbiosome and extracellular regions. Studies of related genes in other species, including acetylcholinesterase and GDSL esterase/lipase, connect the family to pungency traits.
