Protein
Tuliposide B-converting enzyme 1, amyloplastic
Organism
Tulipa gesneriana
Function
Lactone-forming carboxylesterase, 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 B > 6-tuliposide A.
Similarity
Belongs to the AB hydrolase superfamily.
