Rarely, the insertion codes are in reverse alphabetical order. An example is [http://firstglance.jmol.org/fgij/fg.htm?1ucy 1ucy] ([[1ucy]]). Chain L begins with nine amino acids all numbered 1. The insertion codes are in '''reverse-alphabetic order''': 1H, 1G, 1F, ... 1B, 1A, 1, 2, 3 .... In the same chain L are fourteen residues numbered 14. These insertion codes are in '''forward alphabetic order''': 13, 14, 14A, 14B, ... 14L, 14M, 15, 16 .... | Rarely, the insertion codes are in reverse alphabetical order.

There are also ten residues numbered 60, with forward-alphabetic insertion codes from A through I. | ||
