Recently I read some information about succinate dehydrogenase, which reversiably converts succinate into furmate. This kind of enzyme always contain four subunits: A subunit is succinate binding site attached with FAD; B subunit contains three iron-sulfur clusters; Subunit C and D are hydrophobic membrane anchor subunits, containing one heme b group and a ubiquinone-binding site.
I don't know is it possible to recombinant express only subunitA for activity test?
Every suggestion is welcome!
Thanks in advance!
