✦ Synopsis

The N-terminal headpiece, MAKVQAYVSDEIVYKINKIVER, of the TraM protein exists in two distinct conformers in a waterÈSDS mixture. 1H NMR investigations and X-PLOR calculations revealed that one of the conformers has a helical structure whereas in the other conformer the helical structure is bent at E-11. The two structures are characterized by di †erent chemical shifts for the Ha and NH protons of S-9 and D-10. 1998

The large dipole moment of globular proteins has been well known because of the detailed studies using dielectric relaxation and electro-optical methods. The search for the origin of these dipolemoments, however, must be based on the detailed knowledge on protein structure with atomic resolutions. A

The structural characterization of heterogeneous catalysts remains difficult. In the late eighties, Feher and later others showed that polyhedral oligomeric silsesquioxanes (POSS) can be used to model the surface structure of partially dehydroxylated silica and therefore infer information about the
