2.A.56.1.9
The possible disulfide 3,3'-dithiodipropionic acid (DTDP) tripartite transporter, DctMPQ (Wübbeler et al. 2014).  More probably takes up an array of oxidized sugar onic acids, D-gluconate, D-galactonate, L-arabonate, D-fuconate and D-xylonate. The sugars are oxidized by a broad-range, membrane bound sogar oxidase.  The acids that have been studied kineticall have Kms between 8 and 15 μM (Meinert et al. 2017; ).
