| EC | 4.2.99.23 | ||
| Accepted name: | tuliposide B-converting enzyme | ||
| Reaction: | 6-tuliposide B = tulipalin B + D-glucose | ||
| Glossary: | 6-tuliposide B = 6-O-[(3S)-3,4-dihydroxy-2-methylenebutanoyl]-D-glucose tulipalin B = (4S)-4-hydroxy-3-methylideneoxolan-2-one |
||
| Systematic name: | 6-tuliposide B D-glucose-lyase (tulipalin B-forming) | ||
| 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. | ||
