Functional domains of Brevibacillus thermoruber lon protease for oligomerization and DNA binding: role of N-terminal and sensor and substrate discrimination domains.

Abstract excerpt

Lon protease is a multifunctional enzyme, and its functions include the degradation of damaged proteins and naturally short lived proteins, ATPase and chaperone-like activities, as well as DNA binding. A thermostable Lon protease from Brevibacillus thermoruber WR-249 (Bt-Lon) has been cloned and characterized with an N-terminal domain, a central ATPase domain that includes a sensor and substrate discrimination...
