| 41. | The peptide backbone dihedral angles ( ?, ? ) are about ( 140? 135?) in antiparallel sheets.
|
| 42. | On the other hand, the negative value indicating that any electron's magnetic moment is antiparallel to its spin.
|
| 43. | The major folding motif of protein F is the eight-stranded antiparallel beta barrel common to many viral capsid proteins.
|
| 44. | When they are parallel or antiparallel the interaction is strongest, when they are perpendicular there is no interaction at all.
|
| 45. | For example, the ?-hairpin motif consists of two adjacent antiparallel ?-strands joined by a small loop.
|
| 46. | The overall structure consists of antiparallel ?-sheets and a central seven-stranded cone-shaped ?-barrel.
|
| 47. | Calcium-binding EGF-like domains are typically composed of 45 amino acids, arranged as two antiparallel beta sheets.
|
| 48. | The spin anisotropy manifests itself as an energy barrier that spins must overcome when they switch from parallel alignment to antiparallel alignment.
|
| 49. | It is present in most antiparallel ? structures both as an isolated ribbon and as part of more complex ?-sheets.
|
| 50. | The structure contains typical SH2 domain, with two ?-helices and three antiparallel ?-strands on each SH2 domain.
