The orientation of beta-sheets in porin. A polarized Fourier transform infrared spectroscopic investigation.

Abstract

The orientation of the protein secondary structures in porin is investigated by Fourier transform infrared (FTIR) linear dichroism of oriented multilayers of porin reconstituted in lipid vesicles. The FTIR absorbance spectrum shows the amide I band at 1,631 cm-1 and several shoulders around 1,675 cm-1 and at 1,696 cm-1 indicative of antiparallel beta-sheets… (More)
