Justification for analogy
The motif in 1ovm: compared with d1dhs__ (same superfamily, same cofactor-binding mode), a helix-to-strand transition generated the motif. The motif in 1914: core motif, comparing the two homologous domains (SRP9 and SRP14). Strictly speaking, the motif in 1ovm is not a hybrid motif. However, since 1ovm is a Rossmann-like structure while 1914 is apparently not, these two motifs 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.
