If you wish to remove or add enzymes, click the Add/Remove Enzymes button at the bottom of the view. This will present the same dialog as shown in figure 30.49 with the enzyme list shown to the right.
If you wish to extract a subset of an enzyme list:
open the list | select the relevant enzymes | right-click | Create New Enzyme List from Selection ()
If you combined this method with the filter located at the top of the view, you can extract a very specific set of enzymes. E.g. if you wish to create a list of enzymes sold by a particular distributor, type the name of the distributor into the filter, and select and create a new enzyme list from the selection.
