Rarely, sequence numbers do not increase monotonically from N to C terminus. An example<ref>Thanks to Rachel Kramer Green of [[RCSB]] for this example.</ref> is [http://firstglance.jmol.org/fgij/fg.htm?4zwj 4zwj] ([[4zwj]]). In this chimeric protein, chain A is numbered 1002-1161 continuing 1-326 continuing 2012-2361. That is, there are sudden jumps in numbering of consecutive amino acids: 1161 to 1, and 326 to 2012. At right is an excerpt from the ATOM records of the [[PDB file]] for 4zwj chain A. | Rarely, sequence numbers do not increase monotonically from N to C terminus.
