substrate almost matches the P5 to P1 residues of matriptase zymogen: P5(Thr)-P4(Lys)-P3(Gln)-P2(Ala)-P1(Arg). The hydrolysis of the substrate is expected to mimic the situation of activation cleavage of matriptase zymogen |

relative activity: 19% using engineered L-matriptase (secreted variant of matriptase activated by recombinant enterokinase), relative activity: 16% using engineered pseudozymogen His6t-S-CD (consisting of a spacer and the catalytical domain with an N-terminal His6-tag and a cleavage site for activation by enterokinase) |
