name: peptide cross-linking via 2-imino-glutamic acid 5-imidazolinone glycine
namespace: biological_process
type: go
obsolete: False

Description: The formation of the non-fluorescent protein chromophore cross-link from the alpha-carboxyl carbon of residue n, a glutamic acid, to the alpha-amino nitrogen of residue n+2, a glycine, and a dehydration to form a double bond to the alpha-amino nitrogen of residue n+1. This cross-linking is coupled with a dehydrogenation of residue n+1 to form a double bond between the alpha and beta carbons. This modification is found in the GFP-like non-fluorescent red chromoprotein from the sea anemone Radianthus macrodactylus.
