Making the following substitutions and choosing the relevant (saturable) root gives us: This is the quadratic velocity equation, sometimes also called the tight-binding equation or the Morrison equation ( 1 ). As the KM becomes larger than [ ET ], the curve ... Enzymes with single-substrate mechanisms include isomerases such as triosephosphateisomerase or bisphosphoglycerate mutase, intramolecular lyases such as adenylate cyclase and the hammerhead ribozyme, an RNA lyase. However, some enzymes that only have a single substrate do not fall into this category of mechanisms. Catalase is an example of this, as the enzyme reacts with a first molecule of hydrogen peroxide substrate, becomes oxidised and is then reduced by …
