Tulipa gesneriana (Garden tulip). Tuliposide A-converting enzyme b2, amyloplastic
(from Uniprot) Lactone-forming carboxylesterases, specifically catalyzing intramolecular transesterification, but not hydrolysis. Involved in the biosynthesis of tulipalins, defensive chemicals that show antimicrobial activities against a broad range of strains of bacteria and fungi. Substrates are 6-tuliposide A > 6-tuliposide B. 6-tuliposide A and tuliposide A-converting enzyme, which are compartmentalized in the vacuoles and plastids respectively, come into contact with each other for the enzyme reaction releasing toxic tulipalin A upon cell disruption by pathogen infection or herbivore predation.
Family : Plant_carboxylesterase
Block : H
