Since AP-1 positively regulates Blimp-1 gene expression, repression of Blimp-1 by Bcl-6 was implemented by having Bcl-6 impinge upon the activation step of Blimp-1 gene, thus curbing the maximal induction of Blimp-1 by AP-1.
The activation step, catalyzed by an aminoacyl tRNA synthetase specific for a particular amino acid, effects the formation of an aminoacyl AMP complex [88a] in a manner somewhat analogous to reaction [77]; ATP is required, and inorganic pyrophosphate is a product.
Therefore, we hypothesized that cortactin synergizes with GST-VCA by displacing it from the nascent branch complex, increasing the rate of the final activation step by accelerating the obligatory release of GST-VCA.
It mainly functions by interfering with the platelet activation step in the primary haemostasis.
The WGS catalyst behavior is modulated by the nature of the inner layer which determines the active species surface population by acting on the water activation step.
Physical activation consisted of the thermal treatment of raw fibers at 950 °C in an inert atmosphere followed by an activation step with CO2 at the same temperature.
The biological activity of the proteinases can be regulated transcriptionally and post-transcriptionally by different TIMPs and by activation steps by the proteolytic cleavage of latent forms.
The final activation step (knuc) was optimized by globally fitting the data from time courses at a range of concentrations of GST-VCA, while fixing all other kinetic parameters.
50 µl reactions were submitted to reverse transcriptase for 30 minutes at 50°C, followed by PCR activation step at 95°C for 15 minutes.
