Justification for analogy
The motif in 1chm: one helix and one strand do not belong to the RNaseH core. The "Creatinase/prolidase N-terminal domain" superfamily has only two proteins, and in the other protein (1n51) the inserted strand and helix are much deteriorated. Strictly speaking, this motif may not be a hybrid, since it is present in all members in this superfamily. However, since d1chma1 and d1g62a_ are drastically different structures, the motif in d1chma1 and the motif in d1g62a_ are very unlikely to be homologs and are probably 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.
