Term Name:	AP4 hapten
Synonyms:	N-({2-[2-(L-cysteinylamino)ethoxy]ethoxy}acetyl)-L-tyrosyl-L-seryl-N-{(3S,6S,9S,12S,15S)-9-benzyl-6-[(2S)-butan-2-yl]-12-(4-hydroxybenzyl)-3-[2-(methylsulfanyl)ethyl]-2,5,8,11,14-pentaoxo-1-oxa-4,7,10,13-tetraazacyclohexadecan-15-yl}-L-threoninamide
Definition:	A heterodetic cyclic peptide comprising a cyclopentapeptide made up from L-seryl, L-tyrosyl, L-phenylalanyl, L-isoleucyl and L-methoionyl residues and cyclised by formation of an ester bond between the carboxy group of the methionyl residue and the side-chain hydroxy group of the seryl residue. In addition, the exocyclic amino group is acylated by an L-cysteinylamino)ethoxy]ethoxy}acetyl)-L-tyrosyl-L-seryl-L-threonyl group.
