antiport) 1 2 Representation of transporters belonging to known families within the Major Facilitator Superfamily (MFS) listed according to TC number with their substrate ranges and modes of active transport indicated. Drug exporters are prevalent in both organisms. The DHA1 Family (2.A.1.2) has 12 members in Sco and nine in Mxa, the DHA2 Family (2.A.1.3) has 49 members in Sco and six in Mxa, and the DHA3 Family (2.A.1.21) has six and seven members in these two organisms, respectively. It is clear that Sco, but not Mxa, has greatly increased its numbers of DHA2 family members, although neither did for DHA1 or DHA3 family members. The order of representation is therefore DHA2 >DHA1>DHA3 in Sco, with huge representation of DHA2 members, but DHA1 > DHA3 > DHA2 in Mxa, with much lower representation overall.
