释义 | BETA Examples of dimerdimer isn’t in the Cambridge Dictionary yet. You can help! The protein shell is built of 90 dimers which have two distinct but similar conformations. For dimers which move thermally, the collision crosssection and reduced mass is higher than for monomers. In (a) the fold of the channel is given, showing the head-to-head -helix dimer. The subunit dimerizes such that the five-stranded -sheets of the monomers juxtapose to form a ten-stranded -sheet in the dimer. Upon autophosphorylation of the activation segment by the partner kinase unit in a dimer, the equilibrium comes to favor the ' closed, activated ' state. Two dimers associate to form the tetrameric enzyme. The various combinations result in over 2 0 functional integrin dimers with different specificities. This is unrealistic, because dimers with two left- or two right-handed building blocks should also form. High pressure studies of energy transfer and strongly coupled bacteriochlorophyll dimers in photosynthetic protein complexes. The large subunits are chloroplast encoded and are arranged as 4 dimers. These are stabilized by mutual interactions within the bound dimer, because monomeric binding does not induce helix formation. Since this construct does not catalyse lactose accumulation, it is unlikely that permease dimers oligomerize. One monomer of each dimer in the heterotetramer is shown in gray for clarity. The ligands on these dimers are mainly histidines. Early on it was clear that metal centres in some dimers in low oxidation states tended to artificially drift apart. These dimers are then considered activated and translocate into the nucleus (3). Some of these results, the ones involving the iron dimer, will be described here. The common characteristics of the novel enzymes are their capability to bypass lesions like pyrimidine dimers. |
