Visualizing active cross-bridges, including those bound to actin in the weak binding states thought to precede strongly bound force producing states, is essential for defining the structural transitions that constitute the working stroke of myosin.
More specifically, the apparent forward rate constant of the transition between the nonforce bearing A-M.ADP.Pi state and the bound, force bearing AM*.ADP.Pi state was reduced in ischemic fibers, suggesting that this transition is commensurate with initial crossbridge activation.
Thus, one can postulate that the cross-bridge cycling kinetics is modified in Myh4 arl/+ mice, inducing an increased time spent by individual myosin heads in a strongly bound force-generating state, and thus conducting to an increased proportion of strongly bound myosin cross-bridges.
Binding forces obtained by these strategies are similar, demonstrating that the biophysical properties of the aptamer on the sensors are independent from the immobilization strategy.
Even the filibuster is pointless because procedures exist that were bound to force Cruz to yield the floor by Wednesday afternoon.
But the repercussions of the current scandal are bound to force hard choices, and the question of whether the church can continue to attract enough qualified candidates for the priesthood while barring women and married men is not likely to go away.
Higher water rates and more municipal restrictions on usage are bound to force the entire industry to transform, said Bob Muir, spokesman for the Los Angeles Metropolitan Water District.
Table 1 The relationship between thermodynamic parameters and binding forces Thermodynamic parameter Binding force ∆S > 0 May be hydrophobic and electrostatic interactions ∆S < 0 May be hydrogen bonds and van der Waals forces ∆H > 0, ∆S > 0 Hydrophobic interactions ∆H < 0, ∆S < 0 Hydrogen bonds and van der Waals forces ∆H ≈ 0 or very small, ∆S > 0 Electrostatic interactions.
Love made them foolish, needy, bound by forces they couldn't explain: I was in love, see.
The footage shows officers killing unarmed men, some of whom were bound and forced to lie face down on the street, before being shot in cold blood.
Upon entering the town's convent, which had been seized as a headquarters, Riley had witnessed Ealdama being bound and forced full of water, while supervised by a contract surgeon and Captain Edwin Glenn, a judge advocate.
