Presence of multiple protein kinase activities in rat liver nuclei
(Elsevier, 1972-02-25)
Protein kinase activity was found in the acidic nuclear protein fraction extracted from rat liver nuclei. Four distinct kinase activities were separated by phosphocellulose and DEAE-Sephadex chromatography. Additional ...
Inhibition of RNA polymerase and formyltetrahydrofolate synthetase activity by 6-chloro-8-aza-9-cyclopentylpurine. Structure-activity relationships
(Elsevier, 1970-04-02)
The structural requirements for inhibition of bacterial RNA polymerase and rabbit liver formyltetrahydrofolate synthetase activity by a series of purine nucleoside analogs related to 6-chloro-8-aza-9-cyclopentylpurine (689) ...
Stimulation of nuclear protein synthesis in rat liver after phenobarbital administration
(Elsevier, 1970-07-13)
When a 40 min pulse of leucine-3H was administered to rats 2 hrs after 75 mg/kg of phenobarbital (Pb), there was a 70% increase above control in labeling of microsomal protein and of a nuclear protein fraction extracted ...
