5-fluorolysine as substrate binding in the active site: computational simulations, the enzyme 5,6-LAM abstracts the hydrogen atom rather than the fluorine at C5 of 5-fluorolysine and subsequent rearrangement mimicking the similar mechanism as the natural substrate of the enzyme
a large-scale domain movement is required for interconversion between the catalytically inactive open form and the catalytically active closed form. The recombinant enzyme (KamDE) containing only E1 is active, but is subjected to suicide inactivation with the substrate
active site structure, overview. A large-scale domain movement is required for interconversion between the catalytically inactive open form and the catalytically active closed form. The recombinant enzyme (KamDE) containing only E1 is active, but is subjected to suicide inactivation with the substrate. Modeling of the closed conformation of the enzyme, domain motions, overview
the closed-state of the enzyme is required to bring the cofactors adenosylcobalamin and pyridoxal 5'-phosphate and the substrate into proximity for the radical-mediated 1,2-amino group migration. This process is achieved by transaldimination of the pyridoxal 5'-phosphate-Lys144beta internal aldimine with the pyridoxal 5'-phosphate-substrate external aldimine
