N-terminal Glu or Gln can cyclize, forming an internal lactam bond. See [https://en.wikipedia.org/wiki/Pyroglutamic_acid Pyroglutamic acid in Wikipedia]. Examples with convincing electron densities include [[1s1a]] and [[2are]]. | N-terminal Glu or Gln can cyclize, forming an internal lactam (isopeptide) bond.
