Rubisco is an enzyme that is involved in the biochemical process of carbon fixation in photosynthesis, but also has an economically important error (photorespiration) which incorporates the wrong molecule (oxygen) into RuBP, therefore wasting the energy captured by the plant and producing toxic downstream products. Rubisco's error rate in carbon fixation ...

Rennet is not an enzyme, but rennin is. Any protease enzyme should be capable of causing milk to coagulate, or prevent gelatin from setting. Examples such as papain and bromelain are all cysteine proteases, and all of them will cause milk to coagulate. The example of fig protease that you mentioned is a cysteine protease (no specific name found, referred ...

First it is important to define what actually an error is. What you call misproduct is actually a right product for a different substrate. The enzyme has a low specificity; but you won't say hexokinase is error prone because it has wide substrate specificity. The question is — is specificity critical? Coming to the example of DNA polymerase, you should note ...

Since chemical reactions are governed by quantum physics, there is a whole lot of products that can come out of mixing together several multi-atom molecules. And all of those will have non-zero probability of occurrence. But this probability is extremely low at normal temperatures, so you don't see those products. Enzymes lower activation energy and so ...

Chris is right here, polymerases are generating sequences, the enzymes your asking about do a single type of reaction, so you would be assessing its activity not its fidelity. A good resource I've found for looking at qc data for enzymes like these are just the product inserts from the manufacturer. NEB for example generally seems to provide sufficient qc ...

Though a moderate inhibitor, high concentrations of grapefruits/grapefruit juice will irreversibly inhibit CYP3A4 - a grapefruit every day is not recommended.
