Of the different glycolytic enzymes, phosphofructokinase (PFK), with its allosteric regulation (it is inhibited by ATP while AMP and fructose 1,6-bisphosphate reversing the inhibition) has been shown to have the greatest control over the oscillations.
Although the function of UCP1 in fish is uncertain, it has been shown that UCP1-like uncoupling activity in fish liver mitochondria is mediated by fatty acids and that it is inhibited by purine nucleotides, analogous to its mediation in Eutherians [ 17].
Interestingly, although MRTF-A nuclear import occurs constitutively in fibroblasts and its rate does not increase upon G-actin depletion, it is inhibited upon overexpression of G-actin (Vartiainen et al, 2007).
It preferentially transcribes DNAs containing single-stranded regions, and it is inhibited by low amounts of the toxin alpha-amanitin; 50% inhibition occurs at an alpha-amanitin concentration of 0.03 mug/ml.
63 The GSK3 is a kinase that has peculiar features: it is constitutively active and extracellular stimulation inhibits GSK3 kinase activity, it is inhibited by phosphorylation, it requires 'primed' phosphorylation of its substrates by other kinases before GSK3 can phosphorylate them, and it mainly plays a role as a negative regulator.
In addition to its reported phospholipase A activity, Rv3802 has significant thioesterase activity, and it is inhibited by tetrahydrolipstatin (THL).
It is inhibited when anti-β subunit antibody, streptavidin and H9 antibody link on the β subunits successively, but is activated when virus was binded.
Riboflavin uptake proceeds via a system whose general properties are indicative of a carrier-mediated process: it is inhibited by substrate analogues, exhibits saturation kinetics, and is temperature-dependent.
On the contrary, signs of it can be detected from the beginning of extra-uterine existence; it reaches a first culminating point at or before the fifth year ("early period"), after which it is inhibited or interrupted ("latency period") until the age of puberty, which is the second climax of its development.
The proteinase has a molecular weight of approx. 28 000 and it is inhibited by alpha 2-macroglobulin, alpha 1-antitrypsin, C-1 inactivatory, soybean trypsin inhibitor and diisopropyl fluorophosphate.
It is important, however, to note that he does not say that a representation really is a "force".[15] Rather, several representations in opposition behave in force-like ways.[16] A representation, then, expresses force only to the degree to which it is inhibited; and it is inhibited by another representation only if the latter is opposed to it in some way.
