Fi factor

Two other proteins are required for efficient inversion by the Hin recombinase. A dimer of a 98-residue helix-turn-helix DNA binding protein called Fis (factor for inversion stimulation), a relative of protein HU,18b must bind to an enhancer, a 65-bp DNA segment. Binding of Fis to the enhancer helps to hold the supercoiled DNA and the recombinase in a correct orientation for reaction.576 595 596 Protein HU is also needed. The same Fis protein binds to an enhancer... [Pg.1573]

The primary reason for citing Eq. (14-204) is the large successful experience base in practical applications. Note that the reduction in allowable gas velocity for small diameters given by the Fi factor is conceptually the same as the effect of using smaller-diameter packing in distillation. Note also that over the range of G/L between 1 and 0.1, the Maharudrayya and Jayanti data show a similar reduction in allowable gas rate to tfie F2 factor in Eq. (14-204). The phenomenon behind... [Pg.97]

ADP and phosphate associated with the Fi factor may form linked ATP without any external energy supply. From the author s point of view, the stage of linked ATP formation is the dead-end form (reaction), implemented in the absence of the H+ ion. Therefore, proton is required for synthesizing an active complex in the Fi factor, which would prevent linked ATP formation with deficient one or two protons. Hence, this linked ATP is more highly ionized and capable of relatively simple formation of complexes (i.e. to be linked). Thus, proton is necessary for ATP release to the matrix, which is usually observed in the experiment. [Pg.75]

Energy is required for linked ATP transfer from the active site of the Fi factor to water or ADP transfer and phosphate from water to the active site. If energy is required for H+ ion transfer through the membrane, the mechanism of ATP release to water may be simply explained according to the idea suggested in paragraph 1. [Pg.75]

For simple geometries-, the variation of b from, element to element can be approximated by a simple mathematical expression and the total intensity found by integration. Otherwisie the easiest approach is to measure the actual thickness of shield. material traversed along a straight line from each source element and add algebraically the separate intensity contributions. The total intensity should be multiplied by a fi factor to allow for tbe forward scattering in the shield. This is usually about a factor of 10 for thick shields. [Pg.215]

For example, for a information processing subsystems consisting of PLCs the fi factor was evaluated in the range of 0.5% < /S < 5%. For subsystems, which contain sensors and executive elements %input/output modules 1% < 8< 50% (Hok-stad 2005). Basic value of /1-factor is specified from a table of score estimations on the basis of lEC 61508 suggestions and expert opinions. [Pg.102]

Let us consider here a simple application of the above-mentioned results. The network is of the Manhattan type described in (Carlier and Lucet 1996 Yeh et al. 2002) and solved in (Tanguy 2007) for the two-terminal availabihfy between opposite nodes, as represented in the inset of Fig. 1. We assume that the individual failure rate of each network s link is equal to X, and that there exists a multiple failure rate A corresponding to events such that all links fail furthermore, the repair rate of each link is given by p.. This is nothing but a fi factor model (Fleming 1974 Rausand and Hoyland 2004), with fi =. Given an... [Pg.1466]

Principal component analysis may also be used as shown in Figure 3.16. The FI factor describing isotope effects have different signs as seen in Figure 3.15. In addition, the dividing line for the C-2 chemical shift is 165 ppm. The C-2 chemical... [Pg.45]
