Figure 5.1: Two expanded serine residues. The residue on the left has been modified to create homoserine.
To contract a label:
1. Using a selection tool, right-click the residue label and select Select Linked Objectsor simply double-click on the
label for the expanded residue, and the associated structure will be selected.
2. Go to Structure>Contract Label.
Figure 5.2: The contracted label.
To ensure that the contracted label includes your changes, you must define a new nickname. For example, you can
define a new nickname 'hSer', which includes the hydroxyl group in the residue definition itself.
Merging sidechains with residue
The Merge Sidechains With Residue feature lets you edit an expanded residue and then integrate those changes into
the residue definition. To merge a side chain:
1. Double-click the residue label to select the residue.
2. Right-click and select Biopolymer>Merge Sidechains With Residue from the context menu. The entire side-
chain is merged with the residue.
