peptide cross-linking via 3-(2-methylthio)ethyl-6-(4-hydroxybenzylidene)-5-iminopiperazin-2-one
id: GO:0051357
name: peptide cross-linking via 3-(2-methylthio)ethyl-6-(4-hydroxybenzylidene)-5-iminopiperazin-2-one
namespace: biological_process
type: go
obsolete: False
Description: The formation of a 2-keto-5-iminopiperazine protein chromophore cross-link from the alpha-amino nitrogen of residue n, a methionine, to the alpha-carboxyl carbon of residue n+1, a tyrosine, and a dehydration to form a double bond to the alpha-amino nitrogen of residue n+2. This cross-linking is coupled with a dehydrogenation of residue n+1 to form a double bond between the alpha and beta carbons.
