Chain A,B (PCHB_PSEAE | Q51507)

molecular function
	GO:0016835	carbon-oxygen lyase activity	Catalysis of the breakage of a carbon-oxygen bond.
	GO:0004106	chorismate mutase activity	Catalysis of the reaction: chorismate = prephenate.
	GO:0016853	isomerase activity	Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
	GO:0016829	lyase activity	Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
	GO:0046417	chorismate metabolic process	The chemical reactions and pathways involving chorismate, the anion of (3R-trans)-3-((1-carboxyethenyl)oxy)-4-hydroxy-1,5-cyclohexadiene-1-carboxylic acid.
	GO:0042864	pyochelin biosynthetic process	The chemical reactions and pathways resulting in the formation of the siderochrome pyochelin (2-(2-o-hydroxyphenyl-2-thiazolin-4-yl)-3-methylthiazolidine-4-carboxylic acid).
	GO:0009697	salicylic acid biosynthetic process	The chemical reactions and pathways resulting in the formation of salicylic acid (2-hydroxybenzoic acid), a derivative of benzoic acid.
