Sentence examples for active the absence from inspiring English sources

Isotopic labeling experiments showed that the pathways producing these two compounds are active; the absence of a measurable signal by LC-MS indicates that their intracellular concentrations fall below the limit of detection (LOD).

Such activities involve active engagement, the absence of extrinsic goals, an element of pretend, and are usually done in an environment where there are very few consequences.

There is no evidence for metal coordination in the XcOGT active site, and hOGT is active in the absence of exogenous divalent cations or in the presence of excess EGTA.

The amino acid substitution studies revealed that substitution of certain amino acids for tyrosine 537 in ERα (and at the corresponding tyrosine in ERβ [ 95]) produced constitutively active ERs (ie ERs fully active in the absence of hormone).

The activity of the enzyme was measured with the latter, because it is fully active in the absence of activation by phenylalanine, simplifying the kinetics.

NΔ11 and NΔ15 enzymes were insensitive to allosteric regulation and highly active in the absence of the activator.

In addition, the presence or absence of O2 has considerable influence on the reactivity in NO conversion by ammonia and samples more active in the presence of O2 are less active in the absence of O2.

GAK was shown to be constitutively active in the absence of phosphorylation of the activation loop.

Nox2 requires co-assembly with not only p22phox, but its p47phox and p67phox subunits for activity, whereas Nox4 has been shown to be active in the absence of p47phox and p67phox [29].

Indeed, CASK activity is inhibited by divalent cations and is constitutively active in the absence of cations.

For example, a self-cleaving ribozyme with maximum activity at pH 4 isolated by in vitro selection, is active in the absence of divalent ions (including Mg2+) [ 37].
