Justification for analogy
The motif in 1o17: compare to d2tpt_2 (same family); two strands are insertions; hybrid motif resulted from a helix-to-strand transition in a Rossmann structure. In 1ir6, comparing d1ir6a_ and d1k20a_ (same superfamily), domain 2 in these two homologs are not exactly the same. Anyway, domain 2 does not have a Rossmann-like structure. So the motif in 1o17 and the motif in 1ir6 are analogs.

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.
