SOBER1 (original) (raw)

SOBER1 is an enzyme that catalyzes the biochemical reaction of deacetylation. The SOBER (Suppressor of AvrBsT-elicited resistance) 1 protein is conserved in plants and it suppresses the plant's ability to carry out the hypersensitive response against infection by certain pathogenic effector proteins from the YopJ family. SOBER1 belongs to the protein superfamily of α/β hydrolases and possesses a canonical serine/histidine/aspartate catalytic triad to carry out the deacetylation reaction. There have been contradicting reports about SOBER1's potential phospholipase activity, with one study claiming phospholipase A2 activity of the protein and another study being unable to reproduce this result.
