The sense of smell is arguably our most primal faculty and also the least understood. Even our own olfactorily impaired species is capable of detecting approximately 10,000 distinct scents [Buck, L. & Axel, R. (1991) Cell 65, 175-187]. To achieve that amazing diversity, mammals have approximately 1,000 olfactory genes, which accounts for approximately 3% of their entire genome [Mombaerts, P. (1...

The present article briefly relates the early history and growth of the Centre for Metalloprotein Spectroscopy and Biology at UEA (University of East Anglia) under the joint directorship of A.J. Thomson and C. Greenwood, and charts the exceptional success that this centre has had in fostering bioinorganic chemistry in the U.K. and the impact that it has had internationally.

The leader (L) peptide is located in the amino-terminal part of the polyprotein of members of the Cardiovirus (which includes Theiler's murine encephalomyelitis virus) and Aphthovirus genera of picornaviruses. Although the function of L is unknown, strain DA of Theiler's murine encephalomyelitis virus with a mutation of L produces a cell-specific restricted infection. We now report that the DA ...

Recent developments in infrared (IR) spectroscopic time resolution, sensitivity and sample manipulation make this technique a powerful addition to the suite of complementary approaches for the study of time-resolved chemistry at metal centres within proteins. Application of IR spectroscopy to proteins has often targeted the amide bands as probes for gross structural change. This article focuses...
