(A) Reaction catalyzed by OMPD.
(B) Turnover of OMP substrate by wild-type OMPD (black) is abolished in the Asp312Asn mutant (red). If the detection limit of the assay is assumed to be 5% of the total signal over 4000 s, the Asp312Asn mutant is at least 1300-fold less active than the wild-type.
(C) Michaelis-Menten kinetics of wild-type OMPD at 25°C.
(D) OMPD is an obligatory dimer of high affinity.
