metabolism | during the reaction, the first observed flavin C4a intermediate at pH below 8.5 is the protonated flavin C4a-hydroperoxide, which loses a proton to become an active flavin C4a-peroxide. Residue His44 plays an essential role in deprotonating the flavin C4a-hydroperoxide and initiating chemical catalysis. Residue His45 has a role in binding reduced FMN | Vibrio harveyi |
