Justification for analogy
The motif in 1d7b: uses part of the Ig core and some inserted strands; hybrid motif. The most important feature in Ig fold is the interlock composed of strands 2, 3, 5, 6 (if strands in a classic Ig are numbered from 1 to 7), like two scissors arranged mouth-to-mouth. The motif in 1svb: the first domain in 1svb is almost all meander, so it cannot be homologous to Ig-like proteins.

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.
