pubmed:abstractText |
Ten fragments of vasoactive intestinal peptide (VIP) were tested for reactivity with a human catalytic autoantibody that cleaves full-length VIP(1-28) at the Gln16-Met17 peptide bond. A large COOH-terminal subsequence, VIP(15-28), was bound by the autoantibody with high affinity (Ki 1.25 nM), suggesting that it is the antibody binding epitope. VIP(22-28), a short subsequence distant from the scissile bond, inhibited the binding (Ki 242 microM) and hydrolysis (Ki 260 microM) of full-length VIP by the catalytic autoantibody in a competitive fashion. The autoantibody did not show detectable binding of short VIP subsequences that encompass the scissile bond (VIP(15-21), VIP(11-17), and VIP(13-20]. These data show that residues 22-28, located four amino acids distant from the scissile bond, contribute in recognition of VIP by the catalytic autoantibody.
