Abstrakt: Comparison of the precursor sequence for several peptide hormones of Xenopus laevisskin revealed a consensus sequence around a single arginine cleavage site which is 100% conserved on four residues Arg-Xaa-Val-Arg-Gly (RXVRG). A tetradecapeptide substrate (Asp-Val-Asp-Glu-Arg-Asp-Val-Arg-Gly-Phe-Ala-Ser-Phe-Leu-NH2) was used as a probe to purify and characterize the putative processing endoprotease. A hydrophobic enzyme was purified at least 9000-fold from Xenopusskin exudate by a four-step procedure.
