Tryptophan dimer
WebTryptophan synthase from Escherichia coli, having a molecular weight of 148000, is also eluted at a position corresponding to an apparently higher molecular weight of 280000. These results are interpreted in the context of other genetic and biochemical information on tryptophan synthase from S. cerevisiae, Neurospora crassa , and E. coli as signifying that … WebNov 16, 2012 · Tryptophan 515 prevents TpoR dimerization in a productive orientation for JAK2 activation. This effect is reversible when secondary site mutations to tryptophan are introduced at certain positions around W515. Dimerization of TMD induced by ligand rotates W515 so that it is displaced from the headgroup region of the membrane to the dimer …

WebFeb 9, 2012 · Salt-bridging arginines flank the excitonically coupled cross-dimer tryptophan “pyramid” responsible for UV-B sensing. Photoreception reversibly disrupts salt bridges, triggering dimer dissociation and signal initiation. Mutation of a single tryptophan to phenylalanine re-tunes the photoreceptor to detect UV-C wavelengths.
