Protein
Salicylate synthase
Organism
Mycobacterium paratuberculosis (strain ATCC BAA-968 / K-10)
Function
Involved in the incorporation of salicylate into the virulence-conferring salicylate-based siderophore mycobactin. Catalyzes the initial conversion of chorismate to yield the intermediate isochorismate (isochorismate synthase activity), and the subsequent elimination of the enolpyruvyl side chain in a lyase reaction to give salicylate (isochorismate pyruvate-lyase activity). In the absence of magnesium, MbtI displays a chorismate mutase activity and converts chorismate to prephenate.
Similarity
Belongs to the anthranilate synthase component I family. Salicylate synthase subfamily.
