The Hepatitis B Virus Ribonuclease H Is Sensitive to Inhibitors of the Human Immunodeficiency Virus Ribonuclease H and Integrase Enzymes [PDF]
PLoS Pathogens, 2013 Nucleos(t)ide analog therapy blocks DNA synthesis by the hepatitis B virus (HBV) reverse transcriptase and can control the infection, but treatment is life-long and has high costs and unpredictable long-term side effects. The profound suppression of HBV by the nucleos(t)ide analogs and their ability to cure some patients indicates that they can push ...

Thermal Adaptation of Conformational Dynamics in Ribonuclease H
PLoS Computational Biology, 2013 The relationship between inherent internal conformational processes and enzymatic activity or thermodynamic stability of proteins has proven difficult to characterize. The study of homologous proteins with differing thermostabilities offers an especially useful approach for understanding the functional aspects of conformational dynamics. In particular,

Folding of an isolated ribonuclease H core fragment [PDF]
Protein Science, 1999 AbstractBased on results from both equilibrium and kinetic hydrogen exchange studies of Escherichia coli ribonuclease HI (RNase H), a fragment of RNase H (eABCD) was designed. The sequence of eABCD contains less than half of the protein's primary sequence and includes the regions that were shown to be the most protected from hydrogen exchange in all ...

Characterization of proteins by means of their buffer capacity, measured with an ISFET-based coulometric sensor-actuator system [PDF]
, 1993 Proteins form the specific selector in many biochemical sensors. A change in one of the properties of such a protein has to be detected by an appropriate transducer, which completes the biochemical sensor.

Purification and Properties of Ribonuclease H of Calf Thymus [PDF]
Proceedings of the National Academy of Sciences, 1973 Ribonuclease H of calf thymus has been purified better than 3000-fold to yield an almost homogeneous preparation. The enzyme, which comprises about 0.03% of the total protein in the initial extract, is a slightly acidic protein (pI = 4.95) of molecular weight of about 64,000, possibly composed of subunits. The enzyme requires a metal ion for activation;

Expression of PEG11 and PEG11AS transcripts in normal and callipyge sheep [PDF]
, 2004 BACKGROUND: The callipyge mutation is located within an imprinted gene cluster on ovine chromosome 18. The callipyge trait exhibits polar overdominant inheritance due to the fact that only heterozygotes inheriting a mutant paternal allele (paternal ...

Adrenal Cortical Ribonuclease H (Hybrid)
Experimental Biology and Medicine, 1975 Ribonuclease Hybrid (RNaseH) from adrenal cortical tissue has been characterized. RNase H specifically degrades the RNA strand of purified RNA:DNA hybrids but is inactive on single- or double-stranded RNA or on DNA. The mode of clevage by RNase H is endonucleolytic, producing oligoribonucleoties with 3'-hydroxyl and 5'- phosphate termini.
