Discussion One of the original goals motivating this structural inves- tigation of the Calvin cycle was to determine whether or not the traditional reactions of the Calvin cycle are capable of sustaining a ... investigate viable pathways in the light, in the dark, and in the dark with the addition of sedoheptulose-1,7-bisphosphatase (nor- mally inactive in the dark). The results of the analysis show that ... primarily from the uncertainty in the definition of the kinetics, both in terms of the form that the rate equation should take, and in the values to be assigned to the associated kinetic parameters....

... provides the residues for binding the coenzyme. The C-terminal domain has a lar- gely a-helical structure, and serves mainly in substrate binding. The active site is located in the interdomain cleft, ... (40–800 mm), and so the choice of the constant level of Fru was not critical for determination of D K m (1.23 ± 0.15). The KIE data in Table 4 are instrumen- tal in delineating the kinetic mechanism ... Considering the uncertainty in the in vivo levels of NADH, Fru and Man-ol1P used, we per- formed a sensitivity analysis in which the effects of changes in intracellular reactant concentrations on the thermodynamic...

Methods: Distribution volumes of [N-methyl- 11 C]mirtazapine in brain regions were estimated using single- ... binding potential in the thalamus, and low binding potentials in the striatum, hypothalamus, and brainstem. Thereafter, we initiated PET studies with arterial sampling in humans and used a single-tissue...

Virus-infected cells trigger the innate immune response by recognizing viral components, including DNA, ssRNA, dsRNA and glycoproteins. This response initiates signaling pathways leading to the induction...
