Marasmius scorodonius extracellular dimeric peroxidase - exploring its temperature and pressure stability.

The temperature and pressure dependent stability and function of MsP1, an uncommon peroxidase from the basidiomycetous fungus Marasmius scorodonius were investigated. To this end, a series of biophysical techniques (DSC, fluorescence and FTIR spectroscopy, small-angle X-ray scattering) were combined with enzymatic studies of the enzyme. The dimeric MsP1 turned out to be not only rather thermostable, but also highly resistant to pressure, i.
