I am aware that each enzyme generate a certain amount of misproducts. This is well documented, for example, for the DNA polymerase.
I am interested in enzyme involved in biochemical processes, so for example methytransferase, oxidoreductase, carboxylase and so on. I have been looking for any reference that could report the error rate or the amount of misproduct for any of these enzymes, but I was not successful.
Does anyone know a reference reporting the error rate, or any other information about the misproduct generate by these enzymes?
EDIT
I will try to clarify a bit better my question. Let's assume that we are considering an enzyme that add a methyl group to a molecule, we can choose propionic acid for example. In theory the correct product would derive from the addition of a methyl to the C3. For the biochemistry study we know that the activation energy is decreased by an enzyme for example by orienting the molecules in the right way to react with the second molecule. Therefore, if the enzyme in question will not be able to orient the molecule in the right way there is a certain probability that there will be a mis-product. For example the methyl group could be added to the C2 and not the C3. Now. the probability for this process is quite low, but it cannot be excluded from happening. My question is, if there is anything known about this type of error rates in the different type of enzymes.
I hope this make things a bit more clear

Lets consider the imagine below that was taken from here
In B you can see the interaction of the active site of the enzyme with a substrate (for the example it does not matter if it is the real substrate or an inhibitor). I would say that among al possible interaction that this active site can make with substrates there are some much more likely than others. An hypothetical chart could be created considering the free energy of the complex enzyme-substrate, higher the free energy lower the stability. Therefore among all possible enzyme-substrate combination we will have just few possibilities that have a low free energy. In the first place we will find the "correct" substrate, then we will find eventual competitors and other molecules that have similar chemical features as the substrate. Even though with low probability these interaction, enzyme-competitors, will happen. This might led to the formation of "unwanted product" that I refereed to in my question as "misproduct".
I am interested in reading some paper that are considering thie phenomenon and also quantify its rate. I am also curious if this phenomenon can happen with different rates in different enzymes.
