additional information
-
Km for NADH is below 4 mM, whereas the substrate-level FAD-dependent portion of the activity shows a Km for FAD of 0.044 mM. kcat for the oxidase reaction in the absence of substrate-level FAD is 4.8/s, while kcat for the reaction in the presence of substrate-level FAD is 11.1/s
