Create enzyme list
CLC Genomics Workbench uses enzymes from the REBASE restriction enzyme database at http://rebase.neb.com19.8.
To create an enzyme list of a subset of these enzymes:
File | New |
Enzyme list (
)
This opens the dialog shown in figure 19.49
Figure 19.49: Choosing enzymes for the new enzyme list.
At the top, you can choose to Use existing enzyme list. Clicking this option lets you select an enzyme list which is stored in the Navigation Area. See section Restriction enzyme list for more about creating and modifying enzyme lists.
Below there are two panels:
- To the left, you can see all the enzymes that are in the list selected above. If you have not chosen to use an existing enzyme list, this panel shows all the enzymes available 19.9.
- To the right, you can see the list of the enzymes that will be used.
Select enzymes in the left side panel and add them to the right
panel by double-clicking or clicking the Add button
(
). If you e.g. wish to use EcoRV and BamHI, select these
two enzymes and add them to the right side panel.
If you wish to use all the enzymes in the list:
Click in the panel to the left | press Ctrl + A
(
+ A on Mac) | Add ()
The enzymes can be sorted by clicking the column headings, i.e. Name, Overhang, Methylation or Popularity. This is particularly useful if you wish to use enzymes which produce e.g. a 3' overhang. In this case, you can sort the list by clicking the Overhang column heading, and all the enzymes producing 3' overhangs will be listed together for easy selection.
When looking for a specific enzyme, it is easier to use the Filter. If you wish to find e.g. HindIII sites, simply type HindIII into the filter, and the list of enzymes will shrink automatically to only include the HindIII enzyme. This can also be used to only show enzymes producing e.g. a 3' overhang as shown in figure 19.50.

If you need more detailed information and filtering of the enzymes, either place your mouse cursor on an enzyme for one second to display additional information (see figure 19.51), or use the view of enzyme lists (see Restriction enzyme list).
