Term Name:	obsolete peptidyl-dehydroalanine biosynthetic process from peptidyl-tyrosine or peptidyl-serine
Synonyms:	peptidyl-dehydroalanine anabolism from peptidyl-tyrosine or peptidyl-serine, peptidyl-dehydroalanine formation from peptidyl-tyrosine or peptidyl-serine, peptidyl-dehydroalanine synthesis from peptidyl-tyrosine or peptidyl-serine
Definition:	OBSOLETE. The formation of peptidyl-dehydroalanine from either peptidyl-tyrosine by phenyl transfer, or from peptidyl-serine, which is coupled with the formation of 5-imidazolinone by the two neighboring residues, produces an 4-methylidene-imidazole-5-one active site of some amino acid ammonia-lyases; the 4-methylidene-imidazole-5-one, is formed autocatalytically by cyclization and dehydration of the sequence ASG.
