effects of water-water hydrogen bonding types upon the activity of the enzyme ribonuclease t1 through perturbation of the water hydrogen bonding distribution by using various salts, overview. Various salts differ in their ability to reduce the enzymatic activity of ribonuclease t1 correlated with the ability of each salt to promote high-angle hydrogen bonding in water. Increasing the population of high-angle hydrogen bonds among water molecules stabilizes the more compact, less active conformations of the enzyme

neither the native nor N-terminal extended form of RNase G can restore the growth defect associated with either the rne-1 or rneD1018 alleles, encoding RNase E, even when expressed at very high protein levels. In contrast, two distinct spontaneously derived single amino acid substitutions within the predicted RNase H domain of RNase G, generating the rng-219 and rng-248 alleles, result in complementation of the growth defect associated with various RNase E mutants. Complementation of the growth defect associated with RNase E-deficient strains is dependent on the intracellular level of the Rng-219 and Rng-248 proteins

comparison of the electrostatic potential of the molecular surfaces of RNase Po1 and RNase T1 shows that RNase T1 is anionic whereas RNase Po1 is cationic, so RNase Po1 might bind to the plasma membrane electrostatically, determination of the three-dimensional X-ray structure of RNase Po1 and comparison to that of RNase T1. One of the additional disulfide bond is in the catalytic and binding site of RNase Po1, and makes RNase Po1 more stable than RNase T1. The base recognition site of RNase T1 consists of Tyr42, Asn43, Asn44, Glu46, Tyr45, and Asn98 and is located in the loop between beta3-4 strands (Asn43, Asn44, Tyr45, Glu46) and in the loop between beta6-7 strands (Asn98). In case of the base recognition site of RNase Po1, the amino acid residues Tyr38, Asn39, Asn40, Phe41, Glu42, and Asn94 correspond to those of RNase T1

additional information
two extended replica-exchange molecular dynamics simulations on RNase T1, each with different histidine protonation states, corresponding to pH 6 and pH8. At high pH, the appearance of partially unfolded states is evident. This pH-induced destabilization originates from increased global repulsion as well as reduced local favorable electrostatic interactions and reduced H-bonding strength of His27, His40, and His92. At high pH, alternative tryptophan rotamers appear and are linked to a distorted environment of the tryptophan, which also acts as a separate source of ground-state heterogeneity
