Choose correct statements about thermophilic proteins
I. The proteins found in thermophilic species are much more stable than their mesophilic counterparts.
II. All thermostable proteins have such a high incidence of salt bridges
III. the most important of which are an increased size of the protein’s hydrophobic core, an increased size of the interface between its domains and/or subunits, and a more tightly packed core as evidenced by a reduced surface-to-volume ratio.
IV. Several of these thermostable enzymes have a superabundance of salt bridges on their surfaces.
