Chain A,B (SABP2_TOBAC | Q6RYA0)

molecular function
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0016298	lipase activity	Catalysis of the hydrolysis of a lipid or phospholipid.
	GO:0080031	methyl salicylate esterase activity	Catalysis of the reaction: methyl salicylate + H2O = salicylic acid + methanol + H+.
biological process
	GO:0006952	defense response	Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
	GO:0002376	immune system process	Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
	GO:0045087	innate immune response	Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
	GO:0008152	metabolic process	The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
	GO:0009862	systemic acquired resistance, salicylic acid mediated signaling pathway	The series of molecular signals mediated by salicylic acid involved in systemic acquired resistance.
