31. Additional subunits that appear to lack catalytic activity may be present in the ATPase complex. 32. In biochemistry, enzymes are a good thing, but controlling their catalytic activity is even better. 33. The porous structure left behind has a large surface area, which gives high catalytic activity . 34. Research into Pipe's catalytic activity eliminated the likelihood of it being a heparan sulfate glycosaminoglycan. 35. Berzelius had defined the word " ferment " as being an example of catalytic activity . 36. This compound has also been shown to have similar catalytic activity to that of catalase. 37. Acetylation of yeast Rtt109 at Lys290 is also required for it to exhibit full catalytic activity . 38. Magnesium is a necessary cofactor, without which the synthase displays a complete lack of catalytic activity . 39. A false positive can result from the presence of substances with catalytic activity similar to heme. 40. DNMT3L is a protein that is homologous to the other DNMT3s but has no catalytic activity .
