AtDVR is able to efficiently convert 3,8-divinyl chlorophyllide a to 3-vinyl chlorophyllide a with higher reaction velocities. In addition, the AtDVR enzyme is also able to convert 3,8-divinyl protochlorophyllide a and divinyl magnesium-protoporphyrin IX monomethyl ester into monovinyl protochlorophyllide a and monovinyl magnesium-protoporphyrin IX monomethyl ester, respectively.
