Justification for analogy
The motif in 1p5g: comparing the three duplicates, the first two strands are insertion. Hybrid motif. Since the three domains apparently have a mini-Rossman core, this motif can be used as analog to a+b motifs.

In the alignments below, two upper-case letters are aligned, while two lower-case letters are NOT aligned. The two sequences in an alignment are NOT continuous in most cases (see their ranges). The superpositions are re-constructed from the corresponding alignments by minimizing the overall RMSD. In a PDB-format superposition file, the first domain is represented by chain S and the second domain is represented by chain A.
