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 ...
A study of genetic polymorphisms of milk β-lactoglobulin, α S1 -casein, β-casein, and κ-casein in five dairy breeds
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1972-02)
Gene frequencies of the milk β-lactoglobulin, α S1 -casein, β-casein, and κ-casein loci have been estimated from 1663 cows of five dairy breeds. Departure from Hardy-Weinberg equilibrium was found only in the κ-casein ...
Aplanochytrium kerguelensis gen. nov. spec. nov., a new phycomycete from subantarctic marine waters
(Springer-Verlag, 1972-03)
A new monocentric marine fungus, Aplanochytrium kerguelensis gen. nov. spec. nov., was recovered from water samples taken in the vicinity of the Kerguelen Islands in the South Indian Ocean during a cruise of the research ...
Mitotic blockage following laser micro-irradiation of prosphase chromosomes
(Elsevier, 1972-01-22)
An argon laser microbeam was used to irradiate prophase chromosomes of the salamander () and the established cell of the rat kangaroo (PTK1, ). In both cell types mitosis was significantly blocked when irradiation occurred ...
Induced optical activity in rhodopsin analogs
(Elsevier, 1972-05-26)
The Schiff's base derived from 11- retinaldehyde and ( has been synthesized and its CD spectrum measured. Schiff's bases derived from all- retinaldehyde and , and ()-2,2'-diamino-6,6'-dimethylbiphenyl were also prepared ...
Resistance of bacteriophage PBS2 infection to rifampicin, an inhibitor of RNA synthesis
(Elsevier, 1972-09-26)
The induction of viral enzymes, the synthesis of DNA, and the production of progeny phage during infection of by bacteriophage PBS2 are all unaffected by the presence of rifampicin. Rifampicin, rifamycin SV, streptovaricin, ...
Formation of 3'-32P-acyl CoA from [gamma]-32P-ATP in guinea pig liver mitochondrial extracts
(Elsevier, 1972-01-31)
SummaryA soluble extract that catalyzes the exchange of acyl groups from acyl coenzyme A to coenzyme A has been obtained from guinea pig liver mitochondria. None of several known acyl group acceptors stimulates the transfer ...
On the structure and function of nitrogenase from W5
(Elsevier, 1972-09-26)
Molybdoferredoxin from W5 was fractionated into MoFd with two atoms of molybdenum per 220,000 daltons and a specific activity of 2.6 [mu]moles C2H2 reduced/min/mg protein and into a catalytically inactive species with an ...
The effect of activity on oxygen consumption, oxygen debt, and heart rate in the lizards Varanus gouldii and sauromalus hispidus
(Springer-Verlag, 1972-09)
Oxygen consumption and heart rate were measured during rest and activity in the lizards Varanus gouldii and Sauromalus hispidus . Oxygen debt was calculated from postactive oxygen consumption. Standard metabolic rates of ...
