    摘要： Method of treating a tumor in a mammal comprises administering to said mammal an effective anti-tumor amount of proteases originating from microorganisms. Method of treating a tumor in a mammal comprises administering to said mammal an effective anti-tumor amount of a protease originating from a microorganism which protease is chemically modified by one of the following procedures:
    a) coupling with a saccharide, b) introduction of a hydrophobic polymeric group, c) alteration of electric charge of the protein surface, d) conjugation with a low molecular weight anti-tumor agent of molecular weight less than 2,000, e) formation of dimer or oligomer by cross-linking of protease molecules, f) conjugation with a synthetic polycation, g) conjugation with a synthetic polyanion, and h) combination of the above-mentioned procedures.

    摘要： Catalase and pyranose-2-oxidase may be stabilized according to the invention by means of chemical treatment which render the enzymes resistant to thermal inactivation or inactivation of glucosone or both. Stabilized catalase crosslinked with diimido esters, such as dimethyl suberimidate and dimethyl adipimidate, is described. Stabilized pyranose-2-oxidase amidinated with an amidinating agent, such as ethyl acetimidate, is also described. The invention includes the production of such enzymes and their use in an improved process for producing glucosone from glucose.
