It is the only known photoactive protein that uses a carotenoid, canthaxanthin, as its chromophore. The structure of OCP consists of two globular domains, connected by an unstructured loop, that forms a hydrophobic pocket for the carotenoid. In low light, canthaxanthin bound OCP is inactive and appears orange. Illumination by strong light results in an active state that interacts with the PBS to induce fluorescence quenching, a red appearance and conformational changes that include a 12Å shift by canthaxanthin into the N-terminal domain. Terahertz (THz) dynamical transition measurements and anisotropic terahertz microscopy are used to measure the intramolecular structural dynamics in the inactive and active states, which can be induced by photoexcitation or chaotropic salts. The measurements indicate that the active state has a decrease in structural flexibility, which may be related to enhanced interactions with the PBS.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000513023201290</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: KK8YX&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 0&lt;br/&gt;McKinney, Jeffrey A.

We analyse the dependence of sigma(DC) on E(omega) assuming that electron-optical phonon scattering dominates energy relaxation, that the absorbed power has a Drude form and that the electron distribution is thermal. This simple analysis is self-consistent: Arrhenius plots of the estimated energy loss rate have a slope near -homega(LO)BAR/k(B) for all frequencies, as expected for energy loss by optical phonon emission. We find that the effective energy relaxation time tau(epsilon) varies with the frequency of the applied field, from tau(epsilon) approximately 4 ps at 0.34 THz to tau(epsilon) approximately 0.3 ps at 3.45 THz. This may indicate a frequency-dependent form for the hot-phonon distribution.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NM75300116</style></accession-num><notes><style face="normal" font="default" size="100%">Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;S&lt;br/&gt;8th International Conference on Hot Carriers in Semiconductors&lt;br/&gt;Aug 16-20, 1993&lt;br/&gt;Oxford univ, oxford, england&lt;br/&gt;Sci &amp; engn res council; royal soc; brit council; oxford univ&lt;br/&gt;2</style></notes></record></records></xml>
