If so, they may influence the levels of expression of co-transcribed genes; those elements forming 3' adducts to operons are likely to form stem-loop structures that may impede the action of 3'→5' exonucleases, the primary RNA degradation pathway in bacteria, thereby stabilising the transcript.
Repression, in metabolism, a control mechanism in which a protein molecule, called a repressor, prevents the synthesis of an enzyme by binding to and thereby impeding the action of the deoxyribonucleic acid that controls the process by which the enzyme is synthesized.
She was, of course, fabulously wasted – a lawnmower could have stood in for her without impeding the action.
Furthermore, the uptake of MitoQ into cells [46,47] and its excretion into the bile from the liver in vivo are impeded by the action of P-gp [48].
Mutations in the G-patch of Spp2 impede the action of Prp2 in the spliceosome.
He went on to explain how this witchery would "suffocate, extinguish and cause to perish" pretty much everything we cherish, and if that wasn't bad enough, wet dreams would "impede the conjugal action of men and women".
Thus, increasing the clearance rate for the anti-VEGF and VEGF/anti-VEGF complex impedes the therapeutic action of the anti-VEGF agent in the tumor.
Soluble VEGFR2 fragments can bind endogenous VEGF, thereby blocking the action of VEGF and impeding the binding of VEGFR1, VEGFR2, and VEGFR3 to cell membrane ligands, inhibiting the VEGF-induced signaling pathway, and preventing angiogenesis [ 8].
As Nitschke finished his testimony, he again outlined his support for not impeding the right of competent people to take the "lawful" action of "rational suicide".
Several state governments are impeding the use of this grant through a combination of delayed action and inaction.
