Abstract
THE existence of a urease of low molecular weight has previously been noted1–3 but in circumstances that prevented ready characterization. We have shown that highly purified preparations of jack bean urease can be reversibly and rapidly dissociated without appreciable change in enzyme activity. The preparative molecular weight of 485,000 (ref. 4) is halved in the process.
