Association of DNA polymerase with nucleosomes from mammalian cell chromatin. 1978

E J Schlaeger, and H J van Telgen, and K H Klempnauer, and R Knippers

More than half of the DNA polymerase beta in mouse ascites cell chromatin was found to be associated with monomeric nucleosomal particles (produced by micrococcal nuclease treatment of chromatin). Almost all nuclear DNA polymerase activity in lymphocytes was found to be associated with nucleosomes. The nucleosome-associated enzyme was mainly DNA polymerase beta in chromatin from resting and mainly DNA polymerase alpha in chromatin from concanavalin-A-stimulated lymphocytes.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D002286 Carcinoma, Ehrlich Tumor A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms. Ehrlich Ascites Tumor,Ascites Tumor, Ehrlich,Ehrlich Tumor Carcinoma,Tumor, Ehrlich Ascites
D002843 Chromatin The material of CHROMOSOMES. It is a complex of DNA; HISTONES; and nonhistone proteins (CHROMOSOMAL PROTEINS, NON-HISTONE) found within the nucleus of a cell. Chromatins
D003208 Concanavalin A A MANNOSE/GLUCOSE binding lectin isolated from the jack bean (Canavalia ensiformis). It is a potent mitogen used to stimulate cell proliferation in lymphocytes, primarily T-lymphocyte, cultures.
D003851 Deoxyribonucleases Enzymes which catalyze the hydrolases of ester bonds within DNA. EC 3.1.-. DNAase,DNase,Deoxyribonuclease,Desoxyribonuclease,Desoxyribonucleases,Nucleases, DNA,Acid DNase,Alkaline DNase,DNA Nucleases,DNase, Acid,DNase, Alkaline
D004259 DNA-Directed DNA Polymerase DNA-dependent DNA polymerases found in bacteria, animal and plant cells. During the replication process, these enzymes catalyze the addition of deoxyribonucleotide residues to the end of a DNA strand in the presence of DNA as template-primer. They also possess exonuclease activity and therefore function in DNA repair.

D005033 Ethylmaleimide A sulfhydryl reagent that is widely used in experimental biochemical studies. N-Ethylmaleimide,N Ethylmaleimide
D006657 Histones Small chromosomal proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in cell nuclei by ionic linkages. Classification into the various types (designated histone I, histone II, etc.) is based on the relative amounts of arginine and lysine in each.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012965 Sodium Chloride A ubiquitous sodium salt that is commonly used to season food. Sodium Chloride, (22)Na,Sodium Chloride, (24)NaCl
