Justification for analogy
Comparing d1ds1a_ and d1e5sa_ (same superfamily, different family), one strand and one helix are insertions. Thus the IF3-like motif in d1ds1a_ is a hybrid.

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.
