3.D.6.1.2
The Rnf-type NADH dehydrogenase, RnfABCDEG (Imkamp et al., 2007). Note: RnfD may be truncated as almost all homologues have 300-330aas with 6-7 TMSs.  This system has been shown to pump Na+ out of the cell when reducing NAD+ with reduced ferredoxin, and dependent on the smf for reduction of ferredoxin with NADH2 (Hess et al. 2013).

Protein Name:RnfD
Length:319
Molecular Weight:33734.00
Species:Acetobacterium woodii [33952]
Number of TMSs:10
Substrate hydron
