ENZYME entry: EC 4.2.99.23

Accepted Name
tuliposide B-converting enzyme
Reaction catalysed
6-tuliposide B <=> D-glucose + tulipalin B
Comment(s)
  • The enzyme, characterized from pollen of the plant Tulipa gesneriana (tulip), catalyzes the intramolecular transesterification of 6-tuliposide B to form the antibiotic aglycon tulipalin B as a sole product.
  • It does not catalyze 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.
