Altered Pol II activity through TL defects do not bypass or appear epistatic to the alleles of TFIIB or TFIIF studied here for ADH1 TSS selection, suggesting that they each function separately as part of a concerted process to promote efficient TSS selection.
It is also to be considered that individual PKC isoforms may mutually regulate their activity as part of a concerted process involving a network of signalling cascades [ 30].
This leads us to favour a third scenario according to which Smc3 NBD acetylation and establishment of cohesive structures, which we presume to be co-entrapment of sister DNAs inside cohesin rings, are both aspects of a concerted process involving a major conformational change in the structure of the hinge that is adversely affected by the hinge channel-neutralizing mutations.
In the presence of a range of cycloalkanes, an HDDA reaction led to the production of cycloalkenes through a concerted process; excellent yields were obtained for cyclooctane, -heptane, and -pentane donors.
Alongside other spectroscopic techniques, these experiments provided the first evidence of how an OMP folds, revealing that the folding and membrane insertion of OmpA is a concerted process [143,144].
On the other hand, at a fixed concentration, the variation of the gelation rate with temperature suggests that the gelation is a two step concerted process of conformational ordering and crystallization, the former acting as the rate determining step.
These calculations similarly indicate a concerted, asynchronous process; advanced cleavage of the N O bond is accompanied by significant buildup of partial negative charge at nitrogen.
If this view is correct then GRBs were created by a concerted evolutionary process during which the degree of conservation of individual elements has increased proportionally to the number of elements within the block.
Fig. 8 The total normalized energy of the four possible routes for the oxidation of quinoline in the active site of Qor Fig. 9 The proposed reaction mechanism to probe the feasibility of stepwise or concerted process for the oxidative hydroxylation reaction of quinoline in the active site of Qor.
In our model, the granules occur through a concerted action of the monomeric proteins, which should be followed by another round of concerted process among the preformed oligomeric granules through the structural rearrangement imposed by a physical influence of the shear force (Figure 5).
