DNA-binding protein HUbeta + H2O | Lon binds to both histone-like proteins HUalpha and HUbeta, but selectively degrades only HUbeta in the presence of ATP. Preferred cleavage site is the A20-A21, followed in preference by L36-K37. Degradation of substrate mutants A20D and A20Q is more slowly. Mechanism follows at least three stages: binding of Lon with the HU protein, hydrolysis of ATP by Lon to provide energy to loosen the binding to the HU protein and to allow an induced-fit conformational change, and specific cleavage of only HUbeta | Escherichia coli | ? | - |
