zymogen activation of the enzyme involves sequential autocatalytic processing of its N-terminal prodomain at sites B'/B followed by the C'/C sites. Autocatalytic maturation by sequential cleavages of the N-terminal pro-domain first at sites B'/B (RKVF2RSLK1372), followed by site C (RRLL1862), with crucial roles for R and V/L residues at P4 and P2 (fourth and second residue upstream the scissile bond, respectively). Enzyme autoprocessing results in intermediates whose catalytic domain remains associated with prodomain fragments of different lengths. 9 Amino acid residues at the cleavage site (P1-P8) and P1' are necessary and sufficient to define the subcellular location of processing and to determine to what extent processing of a substrate depends on SKI-1/S1P maturation. Mature enzyme retains prodomain fragments of different lengths, overview. The post-translational modifications are crucial for the subcellular localization of autoprocessing intermediates of the enzyme |
