Comments
Cytochrome c proteins, such as cytochrome cL (PDB; 1umm) and cytochrome c-551i (PDB; 1fi3), which are electron transfer proteins, play a role as a substrate, which accepts two electrons from this enzyme.
Thus, this enzyme catalyzes the following reactions:
(A) Hydride transfer from a primary alcohole to PQQ, giving an aldehyde and PQQH2.
(B) Single electron transfer from PQQH2 to the electron transfer, cytochrome c. (This reaction occurs twice.)
Asp105 and disulfide bond between Cys103-Cys104 might be involved in the electron transfer (see [27]).
