DH-ER

DH Part

The function of DH domain is dehydrating the extended unit and enabling it to form the α, β- enol ester bond. In DH domain catalyzed reactions, the oxhydryls in the extended units and the hydrogen atoms binding to the neighbor carbon atoms are removed by DH domains together and form. After catalysis, α, β-enol ester bonds are formed in the polyketide chains.

ER Part

The function of ER domain is deoxidizing the extended unit and enabling it to form the saturated methylene. The mechanism of ER domain catalyzed reactions is similar to KR domain. In ER domain catalyzed reactions, NADPHs provide hydride ions and ER domains provide protons to the complexes and deoxidize carbon-carbon double bond to form the saturated methylene.
