pressure tuning hole burning experiments using the UV-absorbing tyrosine residues. Ribonuclease A protein stays intact upon cooling to 2 K. Its various tyrosine sites show characteristic features which can be resolved in pressure tuning hole burning spectra. Reducing the sulfur bridges leads to a loss of the individual features, and the sites become alike. The respective compressibility is reduced by more than a factor of 2 and comes close to the value of free tyrosine in solution. Compared to the reduction of the sulfur bridges, the influence of guanidinium hydrochloride on the pressure tuning behavior is less pronounced

use of gene duplication to generate tandem enzymes covalently bound by peptide linker. Tandemization has minor effects on the activity and stability in comparison to monomeric RNase A. Relative activity decreases by 10-50%, and melting temperature decreases by less than 2.5 K.

the structure of bovine pancreatic ribonuclease A variants V47A, V54A, V57A, I81A, I106A, and V108A is solved at 1.4-2.0 A resolution and compared with the structure of wild-type protein. The introduced mutations have only minor influence on the global structure of ribonuclease A. The structural changes have individual character that depends on the localization of mutated residue, however, they seem to expand from mutation site to the rest of the structure. Analysis of the difference distance matrices reveal that the ribonuclease A molecule is organized into five relatively rigid subdomains with individual response to mutation

construction of enzyme dimer composed of monomeric units covalently linked by a single amide bond between the side-chains of residues K66 and E9 by incubation of a lyophilized preparation of enzyme under vacuum at 85°C. Procedure does not induce a significant conformational change, dimer shows an 2fold increase in activity over monomeric enzyme and is not inhibited by the cellular ribonuclease inhibitor protein
additional information
-
cross-linking of enzyme or its covalently linked dimer to polyspermine using dimethyl suberimidate. The in vitro and in vivo cytotoxic activity of treated monomeric enzyme is not higher than that of free polyspermine, but dimeric suberimidate-treated enzyme proves to be a more efficient antitumor agent both in vitro and in vivo
additional information
-
substitution of P114 with residues that strongly prefer a trans peptide bond, like Ala, Gly, results in significant population of the C-terminal domain-swapped dimer under near-physiological conditions of pH 8.0 and 37°C. This is in stark contrast to dimerization of wild-type RNase A, which requires incubation under extreme conditions such as lyophilization from acetic acid or elevated temperature
additional information
-
two RNase A variants, P114G and P93A, have the same global stability yet very different domain-swapping propensity, differences in protection factors suggest differential local dynamics
