Renewed interest in the polyphosphoinositides
(Elsevier, 1984-02)
The significance of the enhanced cellular phosphatidate and phosphatidylinositol turnover which occurs in response to specific extracellular messengers has been the subject of much interest and speculation. Until recently, ...
On the dynamic order of structured Escherichia coli growth models
(Wiley Subscription Services, Inc., A Wiley Company, 1987-04-20)
Reliable dynamic descriptions of cellular growth are important for many practical applications including bioreactor design and control. A chemically structured growth model of Escherichia coli has been formulated and ...
Effect of divalent metal ion binding on the Raman spectrum of ATP in aqueous solution
(Elsevier, 1970-01-23)
The apparent dissociation constants for the secondary H+ of HATP-3, CaHATP-1, MgHATP-1 and ZnHATP-1 were determined by studying the pH dependent frequency of a particular line in the Raman spectrum of ATP. We obtained the ...
Protein tyrosine phosphatases in disease processes
(Elsevier, 1994-12)
Given the importance of tyrosine phosphorylation of proteins in signalling pathways, it is perhaps not surprising that protein tyrosine phosphatases (PTPs) are involved in the pathogenesis of certain human diseases. A PTP ...
What might be right about the causal theory of time
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1977-06)
Atmospheric Co2 And O3 Alter The Flow Of 15n In Developing Forest Ecosystems
(Ecological Society of AmericaWiley Periodicals, Inc., 2007-10)
The role of fish life histories in allometrically scaled food‐web dynamics
(Wiley Periodicals, Inc.R Foundation for Statistical Computing, 2019-03)
Body size determines key ecological and evolutionary processes of organisms. Therefore, organisms undergo extensive shifts in resources, competitors, and predators as they grow in body size. While empirical and theoretical ...
Inhibition of cellular ATP-hydrolyzing activity by tricyclic antidepressants and phenothiazine tranquilizers
(Elsevier, 1975-05-01)
In a variety of cellular and subcellular preparations, total ATP-hydrolyzing activity was potently inhibited by tricyclic antidepressants (TA) and phenothiazine tranquilizers (PT). In leukocytes, preincubation of the cells ...
STATISTICAL TESTS FOR TAXONOMIC DISTINCTIVENESS FROM OBSERVATIONS OF MONOPHYLY
(Blackwell Publishing Inc, 2007-02)
Two routes for synthesis of phosphoenolpyruvate from C4-dicarboxylic acids in
(Elsevier, 1974-08-19)
Mutants of defective in both phosphoenolpyruvate carboxykinase and phosphoenolpyruvate synthetase are unable to use C4-dicarboxylic acids such as succinate and malate as carbon and energy sources for growth. Revertants ...
