Cc7 is a sulfur terminal reductase, that is, it reduces a sulfur-containing compound into a sulfide to generate electrons to be used in electron transport chain. The steps required to for this to occur are as follows.  
The function of Cc7 was determined by using NMR spectroscopy as a mointoring technique to determine the oxidation levels of the protein as more chromate (-2)

-
Chromate (-2) nor chromium are part of Cc7's structure; they are the reactant and the product of the reductase activity of Cc7, respectively. The following steps will elaborate how Cc7 carries out its oxidation.


First, Cc7 must be in its resting state. Here, Cc7 is fully reduced and the chromium (III) ion is reduced to chromate(-2).  
As mentioned previously, Cc7 is a sulfur/metal terminal reductase, an enzyme that reduces a sulfur-containing compounds into a sulfide or reduces heavy metals to generate electrons to be used in electron transport chain

-
To begin thus reaction, Cc7 must be in its resting state (i.e. fully reduced). Chromate(-2) (an oxidized heavy metal) .  


The products of the reaction are chromium(III) and the oxidized protein with three iron(III) hemes.
