This entry includes membrane transporters and represents some 7 of potentially 14-16 TM regions. In many instances, its members forms part of complex I that catalyses the transfer of two electrons from NADH to ubiquinone in a reaction that is associated with proton translocation across the membrane, and in this context is a combination predominantly of subunits 2, 4, 5, 14, L, M and N [1]. In many bacterial species these proteins are probable stand-alone transporters not coupled with oxidoreduction [2].	Domain

A 4'-phosphopantetheine prosthetic group is attached through a serine. This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.	Domain
