  • Abstract For X-ray investigations, RNase-A is crystallized from a mixture of 55% 2-methyl-2,4-pentanediol (MPD) and 45% water. Interactions of RNase-A and amino acids with this solvent have been studied. From the solubilities of amino acids in water and 55% MPD it is calculated that the unfolding of RNase-A in 55% MPD would have a positive free-energy change. RNase-A in 50% MPD and in water has nearly identical CD spectra. After being heated in 50% MPD and cooled, there is nearly complete… CONTINUE READING
