Structural Basis for the Catalytic Mechanism of ATP‐Dependent Diazotase CmaA6
Several diazotases have been reported in recent years, but the detailed catalytic mechanism is unclear. From X‐ray crystallography and Cryo‐EM analysis, we obtained the structure of a diazotase CmaA6, which synthesizes 3‐diazocoumaric acid. Kinetic analysis and computational analysis indicated that CmaA6 catalyzes diazotization via an unprecedented ...
