Nuclear and cytoplasmic deoxyribonucleic acid polymerases from rat nephroma cells. 1975

L A Salzman, and L McKerlie

We have examined the DNA polymerases found in a rat nephroma cell line. Using DEAE- and DNA-cellulose chromatography, we have found two major cytoplasmic DNA polymerases and one major and three minor DNA polymerases from the nucleus. The enzymes were all purified, characterized, and distinguished from each other by several criteria. The enzyme require, for maximal activity, a natural or synthetic double-stranded DNA, four deoxynucleoside, triphosphates, and magnesium. They are inhibited to varying degrees by sodium pyrophosphate, ethidium bromide, and rho-chloromercuribenzoate.

D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D009396	Wilms Tumor	A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.

D011756	Diphosphates	Inorganic salts of phosphoric acid that contain two phosphate groups.	Diphosphate,Pyrophosphate Analog,Pyrophosphates,Pyrophosphate Analogs,Analog, Pyrophosphate
D002460	Cell Line	Established cell cultures that have the potential to propagate indefinitely.	Cell Lines,Line, Cell,Lines, Cell
D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell
D002729	Chloromercuribenzoates	Chloride and mercury-containing derivatives of benzoic acid.
D002846	Chromatography, Affinity	A chromatographic technique that utilizes the ability of biological molecules, often ANTIBODIES, to bind to certain ligands specifically and reversibly. It is used in protein biochemistry.
