Lipases (EC 3.1.1.3) are ubiquitous hydrolases for the carboxyl ester bond of water-insoluble substrates, such as triacylglycerols, phospholipids, and other insoluble substrates, acting in aqueous as well as in low-water media, thus being of considerable physiological significance with high interest also for their industrial applications. The hydrolysis(More)
Synchrotron radiation (SR) techniques are continuously pushing the frontiers of wavelength range usage, smaller crystal sample size, larger protein molecular weight and complexity, as well as better diffraction resolution. The new research specialism of probing functional states directly in crystals, via time-resolved Laue and freeze trapping structural(More)
The chemical basis of the blue-black to pink-orange color change on cooking of lobster, due to thermal denaturation of an astaxanthin-protein complex, α-crustacyanin, in the lobster carapace, has so far been elusive. Here, we investigate the relaxation of the astaxanthin pigment from its bound enolate form to its neutral hydroxyketone form, as origin of the(More)
