[Thermodynamic study of guanylspecific ribonuclease C2].
Guanylspecific RNAse C2 has been studied thermodynamically using a microcalorimetry technique. It is shown that at ph varying from 5,0 to 8,0 the RNAse C2 solution in a cacodylate buffer contains about 30% of monomeric and about 70% of dimeric forms of protein, each of them melting as a single cooperative system. Moreover, studies of the influence of phosphate ions have shown that they stabilize the system by 3-4 degrees and transform it into a monomeric form.
