How do I change the start coordinates for regions of a multi-domain protein sequence?
Create or Open a Protein Sequence
Create or open a protein sequence in SnapGene.
If required, add a feature for each region that requires a separate start coordinate, see Create a Simple Feature.
A multi-domain protein must be annotated with a separate feature for each coordinate region.
In this example we will set the coordinates of the two regions of a XynB-EGFP fusion protein to match the coordinates for each native full-length protein.
Set the Translation Numbering
Select the first feature then click View → Set Translation Numbering.
Enter a new start coordinate for the first feature, then click + to set a second start coordinate.
In the second location, click the dropdown to select the next consecutive feature.
Enter the start coordinate for the second feature then click OK.
In Sequence view each feature will be numbered based on the revised translation numbering.
