apoTorA + H2O | Escherichia coli | a molybdoenzyme; immature TorA (apoTorA) is degraded in vivo and in vitro by the Lon protease. Enzyme Lon interacts with apoTorA but not with holoTorA. Enzyme Lon and TorD, the specific chaperone of TorA, compete for apoTorA binding, but TorD binding protects apoTorA against degradation | ? | - |
