This can be explained by the fact that while Leu is a very strong helix former, it also interacts strongly with the hydrophobic hole of the Src SH2 domain, whereas Val has only weak helical propensity, but interacts only weakly with the hydrophobic hole; in both cases, therefore, the two opposing tendencies balance each other, resulting in roughly equal populations.
The moderate tries to preserve the tradition of conflict, keeping the opposing sides balanced.
Rather than having a single "sleep-wake" switch in the brain for controlling our sleep (i.e. ON at night, OFF during the day), we have two opposing systems balanced against each other that go through a daily dance, where each has to wrest control from the other.
Both play important but presumably opposing or balancing roles in the Drosophila circadian system by targeting key clock proteins, such as dPER and CLK (reviewed in, [ 42]).
By balancing these opposing pressures, equilibrium in the chamber was maintained at selected set point pressures to perform calibrations.
Where available and appropriate, governments could also take steps to make the maximum use of such programmes as the EU's STABEX scheme and Sectoral Import Programme27 and the increased availability of foreign exchange assistance (as opposed to balance of payments assistance) could be explored.
Like other balletic kinds of abstraction, including his, Mitchell's art was about opposition and balance: opposing forces held in tense, momentary equilibrium.
The law of electroneutrality states that there must be an equal and opposing charge to balance the positive charge, and so the +40 mEq/l is balanced by an equal negative force comprised mostly of weak acids (ATOT).
How these opposing trends will balance out over time is entirely unclear, experts said.
General aspects of the Balanchine style — dancing off balance, opposing stretched-open positions with tightly closed ones, arriving with the beat rather than following it — have become steadily clearer in recent years.
