ENZYME entry: EC 3.1.1.124

PURL: https://purl.expasy.org/enzyme/EC/3.1.1.124
Accepted Name
ellagitannin acyl hydrolase
Alternative Name(s)
ellagitannase
ellagitannin acyl esterase
Reaction catalysed
punicalagin = punicalin + ellagic acid
Comment(s)
  • The enzyme, which has been isolated from the fungus Aspergillus niger, catalyzes a step in the degradation of ellagitannins such as punicalagin, which are phenolic compounds occurring in pomegranates and some tropical trees.
  • It hydrolyzes ester bonds between the D-glucose core and the hexahydroxydiphenic acid groups of ellagitannins, releasing hexahydroxydiphenic acid that undergoes spontaneous lactonization to form ellagic acid.
  • Unlike EC 3.1.1.20, it does not act on gallotannins.
  • More recent studies suggest that the activity may be catalyzed by EC 3.1.4.3.
