                4.2.99.23 tuliposide B-converting enzyme
IUBMB Comments
The enzyme, characterized from pollen of the plant Tulipa gesneriana (tulip), catalyses the intramolecular transesterification of 6-tuliposide B to form the antibiotic aglycon tulipalin B as a sole product. It does not catalyse the hydrolysis of 6-tuliposide B to form a hydroxy acid. The enzyme has marginal activity with 6-tuliposide A. cf. EC 4.2.99.22, tuliposide A-converting enzyme.
