When butene-1 is recovered, a . In this dimer, some binding sites are unable to bind ligands, e.g., binding of tryptophan is blocked . If dimerization of the chimeric receptors occurs, the Xfz3 part of the chimeric protein should be responsible for this dimerization, as no FGF ligand-binding site is present in these receptors. Fibroblast growth factor-2 (FGF2) is a pleiotropic growth factor exhibiting a variety of biological activities. All the geometric configurations of the stationary points on the reactions path were optimized with Gaussian03 employing density functional theory at the B3LYP/6-311G++(d, p) level by energy gradient technique. (c) Below pH 6.0, histidine protonation may modify the electrostatic surface potential at the dimer interface. Ethylene dimerization is a chemical reaction in which two ethylene molecules combine to form butene molecules. Just as you can take two atomic orbitals, say two hydrogen 1s orbitals, and form a bonding orbital and an antibonding orbital, using three atomic orbitals on three atoms a bonding interaction consisting of three molecular orbitals (one bonding, one nonbonding, and one antibonding). The EGF receptor mediates many cellular responses in normal biological processes and in pathological states. Borane dimerization can be thought of by invoking three-center two-electron bonding. DNA polymerase can bind to such species and extend the primers in both directions to produce an undesired product with a length that is slightly less than the sum of the lengths of the forward and reverse . dimer 1. a compound formed by combination of two identical simpler molecules.
