41. Most dimers in biochemistry are not connected by covalent bonds. 42. Manganese is bound by the calprotectin dimer at this His 6 site. 43. They speculated that the dimer may coordinate rearrangement of the transmembrane helices. 44. This image shows that DAHP synthase consists of two tightly bound dimers . 45. Where C represented a covering of a lattice by nearest neighbor dimers . 46. The crystal structure of CXCR4 dimer was published in 2010. 47. Both these dimers cooperate to slide along microtubules and maintain bipolar spindles. 48. Chemically, it is a dimer of chlorine monoxide ( ClO ). 49. The application is similar to that for alkyl ketene dimers . 50. During polymerization, the tubulin dimers are in the GTP-bound state.
