In CEPS, at least two peptide fragments. CEPS uses an enzyme that has a cysteine in its active site, which gives it the ability to ligate. The first fragment is created with an oxo- or thioester at the C-terminus, which combines with the enzyme’s cysteine in the active site to create a covalent thioester connection and release organic alcohol. The thioester is replaced at the active site by the insertion of the second (amine) fragment, which then links to the first fragment to create the product.
