Justification for analogy
The motif in 1uou: it uses two helices in the N-terminal all-alpha domain, one insertion helix in the Rossmann-like domain, and the crossover helix of the Rossmann domain. So it is a hybrid motif.

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.
