So we have transamination. transamination is catalyzed by an enzyme known as aminotransferase, and we also call it transaminase. But in this lecture, we're going to refer to it as simply aminotransferase. Now, Aminotransferase, as we'll talk about in more detail in the next lecture, uses an important coenzyme, a vitamin B six derivative known as peridoxylphostate. So a periodoxyl phosphate needs to be present for this enzyme to actually be effective. If we have deficiency in this coenzyme here, this enzyme will not function correctly.
