31. The formation of tetramer after modification of thymidine kinase 1 after synthesis enhances the enzyme activity. 32. As a tetramer , the catalytic efficiency of treX is increased fourfold over its dimeric form. 33. Once the tetramer is inserted into the cell membrane, two mechanism of actions can occur. 34. The resulting pMHC-streptavidin-fluorophore tetramer can be added to a sample of cells. 35. 1-Phosphofructokinase is a tetramer of 4 identical subunits that each have a catalytic site. 36. It is a tetramer composed of 1 alpha, 1 beta, and 2 gamma chains. 37. The neon tetramer takes the form of a tetrahedron with sides around 3.2 ? 38. Class I RNR comprises RNR1 and RNR2 subunits, which can associate to form a heterodimeric tetramer . 39. Only two of these sites in the tetramer need to be occupied to open the ion channel. 40. It is a member of the unsaturated polycyclic hydrocarbons class of compounds and a tetramer of benzyne.
