Bilirubin Reductase from Mediterraneibacter gnavus: Positional Reduction Preferences and Transient-State Analysis.
Single-turnover data correlated with steady-state assays and NMR tracking of the steady-state reaction confirm that BilR can reduce both types of vinylic bonds of bilirubin but appears to have a 4-fold preference for reduction of α-vinylic over enamine bonds that is defined almost entirely by the rate of hydride transf...
