We also considered alpha-helical properties and turn tendencies, which could affect the formation of TMHs.
Two additional properties (Alpha-helical tendencies and Turn tendencies) are given due to their potential importance to transmembrane helix formation.
(root mean square) fluctuation displacement (F), solvent accessible reduction ratio (Ra), total non-bonded energy (Et) and turn tendencies (Pt), and involves only the OS-E protein.
Properties under positive destabilizing selection (the power to be at the N-terminal, refractive index, long-range non-bonded energy, coil tendencies, compressibility, turn tendencies and the power to be at the C-terminal) will interfere both at a chemical and structural level.
This hypothesis is bolstered by the observation that, similar to the M COX2h+M COX1 and F COX2+F COX1 regions, two amino acid properties related to transmembrane helix formation (alpha-helical and turn tendencies; Table 3) were found to be evolving under either neutral or purifying selection acting to preserve the physicochemical properties of M COX2e.
Of course, a skier can make different types of turns with any ski, but turn radius suggests the natural turning tendency of the ski on "auto-pilot," so to speak.
Although subjects did have small differences in the strength of their left and right legs, the researchers found, these differences didn't correlate with their turning tendencies.
The center knob can be twisted left or right to cancel out any subtle but constant turning tendencies — if your Chopper always seems to be turning slightly to the right, for example, you can bump the center knob to the left to compensate.
The reason was not that the hornet would have decelerated its flights, but its turning tendencies deviated much stronger, so that its direction fidelity dropped after the onset of shimmering, which is documented in the x-y plane of scenario A (Fig. 9C, blue symbols).
For people with Williams syndrome, the ability to bond quickly with strangers is part benefit and part handicap, since they typically can't turn this tendency off, even when they encounter strangers the rest of us would deem a threat.
