To obtain high quality time-resolved ultraviolet resonance Raman (UVRR) spectra of transient intermediates in the bacteriorhodopsin (BR) photocycle, we developed a new UVRR spectrometer. A home-made F=3.5 prism prefilter was used in front of a 50 cm CCD detected spectrograph to give high throughput, wide tunability, and excellent stray light rejection along with low dispersion. Using this system, we obtained 239.5 nm excited time-resolved UVRR spectra of BR which revealed small but significant features associated with the formation of the KL-intermediate at 10 ns delays. This difference spectrum exhibits intensity decreases at 1624, 1561, 1012 and 763cm-1 due to an altered environment of one or more Trp residues and a frequency shift of the Tyr ʋ8b band at 1602 cm-1. These signals show that the photoisomerization of retinal from all-trans to 13-cis induces significant changes in the structure and environment of aromatic residues that line the retinal binding pocket in only 10 ns.

An opsin gene (ops) has been characterized from Leptosphaeria maculans, the ascomycete that causes blackleg disease of Brassica species. This is the second opsin identified outside the archaeal and animal kingdoms. The gene encodes a predicted protein with high similarity (70.3%) and identity (53.3%) to the nop-1 opsin of another ascomycete Neurospora crassa. The L. maculans opsin also has identical amino acid residues in 20 of the 22 residues in the retinal-binding pocket of archaeal opsins. Opsin, on the fourth largest chromosome of L. maculans and 22 cM from the mating type locus, is the first cloned gene to be mapped in L. maculans. Opsin is transcribed at high levels in mycelia grown in the presence and absence of light; this pattern is in contrast with that of the N. crassa opsin, which is transcribed only in the light.Key words: opsin, Phoma lingam, Brassica napus.
