WebOct 6, 2024 · Inactive enzymes have NO affinity for substrate and no activity either. We can’t measure Km for an inactive enzyme. The enzyme molecules that are not bound by methotrexate can, in fact, bind folate and are active. Methotrexate has no effect on them and their Km values are unchanged. Webproteolytic enzyme pepsin, the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products. Pepsin is the mature active form of the zymogen (inactive protein) pepsinogen. Pepsin was first recognized in 1836 by the German physiologist Theodor Schwann.
