Interestingly, this proline residue is located within a [beta] barrel (a protein motif consisting of an antiparallel [beta] sheet domain) and does not appreciably alter the predicted protein structure, as shown by the absence of any substantial changes in the computer-modeled, 3-dimensional structure compared with the HA1 of A/Wyoming/3/2003. It is wired such that a switch can be used to put the coils "in phase," to generate magnetic fields, or in the "bucking mode," in which the two sets of coil are activated in an antiparallel direction (with the same current as in the in-phase condition) to cancel the fields generated by each other. Sections stained with Congo red dye demonstrated the characteristic yellow and apple-green birefringence, and the lesion had the beta-pleated sheet structure and antiparallel conformation by low-angle x-ray diffraction, typical of amyloidosis. |
