Some detergents refer to 'Pectinase', others refer to 'Pectate Lyase'. Both do the same job - break down stick fruit juice stains (apple juice, grapefruit juice).
I had wondered about the Glycosidases, as some detergents listed it two or three times. I presumed they were modified to perform differently.
I remember P&G's 'What's in the box' ingredients list, suggested that one version of the glycosidase enzyme would work on starch stains, and the other would attack pectin stains.
