The present invention relates to a new IgG-degrading enzyme. Here, the inventors investigated whether the Fc fusion technology could be applied to a therapeutic enzyme of bacterial origin. Particularly, they developed IdeS-Fc fusion proteins as a divalent homodimer (IdeS-Fcdiv) or a monovalent heterodimer (IdeS-Fcmonov), in order to extend the IgG-depleting action of IdeS over time. Both IdeS-Fc efficiently separated monoclonal and polyclonal human IgG into F(ab')2 and Fc fragments, although with slower kinetics than their native counterpart. IdeS-Fcmonov exhibited a seven-fold half-life extension in vivo as compared to IdeS, and a significantly better residual cleavage of human IgG at later time points after injection. Their results provide the proof of concept for the use of an IdeS with extended IgG-hydrolyzing functions in vivo that could rapidly translate to the clinic. Thus, the present invention relates to an IgG-degrading enzyme-Fc fusion protein comprising at least one IgG-degrading enzyme fused to an Fc part of an antibody wherein the Fc part comprises at least one mutation.
