Unusual sequence numbering
The numbering of protein and nucleic acid sequences is arbitrary in structure files from the World Wide Protein Data Bank (PDB). Here are some examples. These PDB entries are not shown here. To explore these, the links below will display them in FirstGlance in Jmol (link with arrow) or in Proteopedia.
Not MonotonicNot Monotonic
Rarely, sequence numbers do not increase monotonically from N to C terminus. An example[1] is 4zwj / 4zwj.
