Studies on DNA precursor metabolism in vaccinia virus-infected mamalian cells

Creator:: Spiro, Craig
Abstract:: Vaccinia virus-infected animal cells have been used to study the interactions between the replication of deoxyribonucleic acid (DNA) and the biosynthesis of its nucleotide precursors. Some antimetabolites that inhibit DNA replication have as their targets enzymes of nucleotide biosynthesis. Furthermore, the disruption of nucleotide metabolism can alter the fidelity of...

Attempted cloning of T4 phage ribonucleotide reductase

Creator:: Booth, Joseph
Abstract:: Ribonucleotide reductase is an important enzyme in the control of DNA replication within the cell. Ribonucleotide reductase exerts its control through enzymatic reduction of nucleoside diphosphates. The bacteriophage T4 enzyme is an example of the class of iron-requiring reductases which also includes E. coli and mammalian ribonucleotide reductases. The two...

Modulation of deoxyribonucleoside triphosphate levels, DNA synthesis rates and fidelity in mammalian cells

Creator:: Martomo, Stella A.
Abstract:: Deoxyribonucleoside triphosphate (dNTP) concentrations measured in cells are not symmetric. dGTP almost always represents only 5-10% of the total dNTP pools in cells. In an in vitro replication system involving semiconservative replication from an SV 40 origin, the mutation frequency of an M13 phagemid replicated by human cell extracts in...

Organization of T4 bacteriophage genes and gene products involved in DNA precursor biosynthesis

Creator:: Wang, Yeong
Abstract:: Bacteriophage T4 gene 42 encodes dCMP hydroxymethylase, an enzyme unique to the deoxyribonucleotide metabolism of T-even bacteriophages. To study biochemical and biophysical properties of the enzyme, as well as the interaction of dCMP hydroxymethylase with other DNA precursor biosynthetic enzymes in vitro, availability of large amounts of the enzyme is...

Large subunit of vaccinia cirus ribonucleotide reductase : affinity chromatography-based purification and photoaffinity labeling

Creator:: Warth, Rainer K.
Abstract:: Ribonucleoside diphosphate reductase (RR) from vaccinia virus was recently cloned and overexpressed rn Escherichia coli. The amino acid sequence identities of the small and large subunits between the mouse and the vaccinia virus reductase are approximately 80 and 72 percent, respectively. In addition, vaccinia virus RR displays similar complex allosteric...

Insights into mammalian DNA replication from analysis of mutations affecting deoxyribonucleotide biosynthesis

Creator:: Mun, Byung-joo
Abstract:: Although the synthesis of DNA precursors is closely coordinated with DNA replication, it is still not clear whether deoxyribonucleoside triphosphates (dNTPs) influence DNA replication independently of their interactions with DNA polymerase catalytic sites. In an effort to understand the extent to which rate and fidelity of DNA replication are regulated...

DNA precu[r]sor compartmentation in mammalian cells : metabolic and anti-metabolic studies of nuclear and mitochondrial DNA synthesis

Creator:: Bestwick, Richard Keith
Abstract:: This dissertation describes an investigation of DNA precursor supply for mitochondrial and nuclear DNA synthesis in HeLa cells and Mouse L-cells. HeLa cells were used for the quantitation of cellular and mitochondrial deoxyribonucleoside triphosphate (dNTP) and ribonucleoside triphosphate (rNTP) pools and of changes in pools in response to treatment with...

Vaccinia virus ribonucleotide reductase : gene sequencing, intracellular localization, and interaction with a DNA-binding protein

Creator:: Davis, Ralph Eugene, 1957-
Abstract:: Vaccinia virus infected monkey kidney cells had been previously shown to have an increased ribonucleoside diphosphate reductase (RR) activity. DNA from mutant virus resistant to hydroxyurea were digested with restriction endonucleases and were shown to have substoichiometric amounts of the Hind III F fragment. Additional information from Southern blotting experiments...
