Accepted Name
tuliposide A-converting enzyme
Alternative Name(s)
6-O-(4 -hydroxy-2 -methylenebutyryl)-D-glucose acyltransferase (lactone- forming)
tuliposide-converting enzyme
Reaction catalysed
6-tuliposide A = tulipalin A + D-glucose
Comment(s)
  • Isolated from the plant Tulipa gesneriana (tulip).
