In practice, however, the resolution of the maps was not sufficient to distinguish density for individual α-helices, without which it was not possible to fix the relative orientation of each GSPII fold relative to the others.
Owing to the strong directed forces operative during collision, deformation typically accompanies metamorphism; rocks metamorphosed in response to continent-continent collision generally have fabrics showing a strong preferred orientation of mineral grains, folds on a variety of scales, and pre-, syn-, and postkinematic porphyroblasts.
The location and orientation of the OB-fold domain in the T. aquaticus Pol III structure suggest that the OB-domain may be able to undergo a domain rearrangement in order to bind downstream template DNA (9).
These results confirm that the pattern of gyrification (position, orientation and degree of folds) is a function of the differential expansion of cortex which engenders predictable, non-uniform tangential pressures resulting in broadly consistent cortical morphology.
Finally, in the absence of crystallographic data for ADAMTS-5 ancillary domains, the crystal structure of ADAMTS-13 (3GHN) [ 24] containing the TS-1, CysR and Sp domains was superimposed on the ADAMTS-5 structure to give an idea of fold and orientation of these domains relative to the Cat/Dis domains.
Altogether, these suggest that the orientation of N-terminal domain (Obg fold) of Obg proteins may be regulated by guanine nucleotides and further that the switch element recognition of GTP-bound configurations can trigger a conformational rearrangement between the domains [24], [25].
8. Place each segment on a separate Kimwipe®, maintaining orientation, and fold an unoccupied portion of the Kimwipe® on top of the mucosal surface to wick away excess PBS.
For example, the periodic dependence of R1 dynamics along the sequence 128 135 in T4L in solution reveals a helical structure of orientation within the fold, as predicted for helix H in the crystal structure.
Conformational differences in the orientation or folding of surface CXCR4 [19], including conformational differences between immune versus breast cells [10], may be functionally important.
Therefore, the orientation and folding of the adsorbed protein become critical factors in determining whether cultured cells will be able to interact with the RGD peptide and thus adhere to the surface.
