3.B.1.1.6
Na+-exporting oxaloacetate decarboxylase with three subunits, OadA (α), OadB (β) and OadG (γ) of 599 aas and 0 TMSs, 433 aas and 11 TMSs, and 90 aas and 1 TMS, respectively.  These three subunits are 72%, 70% and 40% identical to 3.B.1.1.1.  The stoichiometry of the three subunits is 4:2:2, and large amounts of the protein can be generated for crystalographic studies (Inoue and Li 2015).
