Subunit of: YadG/YadH ABC transporter

Subunit composition of YadG/YadH ABC transporter = [YadG]2[YadH]2

Summary:
YadG and YadH are uncharacterized members of the ABC superfamily of transporters [Saurin99]. YadG is the putative ATP binding component, YadH is the putative membrane compenent. Based on sequence similarity, they probably function together as as an ATP-driven efflux system. The genes yadg and yadh are probably located within a single operon.
