Conjugates of soybean trypsin inhibitor (SBTI) and potato serine protease inhibitor (PSPI) immobilized on metal oxide particles of ~100nm diameter were prepared. Inhibition of trypsin hydrolysis of BAPA by these conjugates was measured and enzyme kinetics constants kcat, KM, kcat/KM and ki were determined. Metal oxide particles presented an inhibitory effect similar to that of a competitive inhibitor, noticed through the increase value of the K M constant. Furthermore, PSPI conjugates had the highest inhibition of trypsin, illustrated by the significantly higher value of KM relative to the value for particles only.
