Figure 2. Superposition of Light Framework 3 with an insertion onto a typical LFR3.

Residues L60–L75 of crystal structure 1PW3 (in red), containing an insertion, are superposed onto a typical example of the equivalent Light chain fragment (here 1A4K, in blue). The new insertion point was introduced in position L67 (highlighted in green). Graphics created with Swiss-PdbViewer (http://www.expasy.org/spdbv/).
