EcoRI restriction endonuclease cleavage site map of bacteriophage P22 DNA
(Elsevier, 1978-01-25)
The seven EcoRI restriction endonuclease cleavage sites in bacteriophage P22 DNA have been mapped. The cleavage site map of circularly permuted P22 linear DNA is a circle. The positions of EcoRI sites in the early region ...
Non-visual functions of crustacean eyestalk ganglia
(Springer-Verlag, 1971-03)
Ablation experiments demonstrated that in several crustacean groups, the proximal eyestalk ganglia are important in a variety of behavior patterns: 1. Chemical elicitation of feeding via the antennules is altered in lobsters, ...
Drug inhibitable ecto-ATPase in leukocytes
(Elsevier, 1975-05-01)
In rat leukocytes, the total ATP-hydrolyzing activity was highest when determined in cells with an intact plasma membrane. The ecto-ATPase, exhibiting a Km for ATP of 0.3 mM, was inhibited 30% by sulfhydryl reagents, whereas ...
Estrogen induction of ornithine aminotransferase in rat kidney slices
(Elsevier, 1978-06-14)
Immunologic titration of kidney extracts from control and estradiol-injected rats with anti-ornithine aminotransferase serum shows that the hormone induces the enzyme by increasing its concentration in the kidney. The ...
Photosystem II -- Mediated cyclic photophosphorylation
(Elsevier, 1976-02-09)
DCMU-sensitive synthesis of ATP can be shown to continue in KCN-treated chloroplasts after cessation of O2 evolution. The catalyst for this reaction, -phenylenediamine, also stimulates synthesis of ATP in NH2OH-treated ...
Cadmium metabolism in cdm/cdm mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-08)
The uptake and metabolism of cadmium by cadmium-susceptible ( +/+ ) and cadmium-resistant (cdm/cdm) strains of mice have been compared. These strains did not differ with respect to the quantitative uptake of cadmium into ...
Citrulline metabolism in normal and citrullinemic human lymphocyte lines
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-08)
Citrullinemia is one of the five aminoacidurias associated with the Krebs-Henseleit urea cycle. A long-term lymphocyte line (UM-21) derived from a patient with this disease and nine of ten clones of this line were found ...
Unstable electron pairing and the energy loan model of enzyme catalysis
(Elsevier, 1979-07-21)
A theory of enzyme catalysis is described which utilizes a thermodynamically consistent construction of a free energy diagram with different pathways for complex formation and decomposition. The switch to the decomposition ...
Analysis of selection in populations observed over a sequence of consecutive generations
(Springer-Verlag, 1974-01)
A statistical model is presented for dealing with genotypic frequency data obtained from a single population observed over a run of consecutive generations. This model takes into account possible correlations that exist ...
