Autoantibodies which enhance the rate of a chemical reaction of a substrate, processes for their preparation, their use and compositions thereof are disclosed. In particular, an autoantibody capable of catalyzing the hydrolysis of the peptide bond between amino acid residues Thr7-Asp8, Arg14-Lys15, Gln16-Met17, Met17-Ala18, Ala18-Val19, Lys20-Lys21, Lys21-Tyr22 in the neurotransmitter vasoactive intestinal peptide (VIP) is disclosed. |
