cindoxin
Cdx, UniProt ID Q8VQF4, the FMN-containing redox partner to P450cin. Brownian dynamics-molecular dynamics docking method is used to produce a model of Cdx with its redox partner, enzyme P450cin, overview. Potential importance of Cdx Tyr96 in bridging the FMN and heme cofactors as well P450cin Arg102 and Arg346. Arg346 plays an important role in electron transfer. Arg102 also interacts with a P450cin heme propionate. Redox partner binding stabilizes the open low-spin conformation of P450cam and greatly decreases the stability of the oxy complex.
