9.A.5 The Putative Arginine Transporter (ArgW) Family
The putative arginine transporter (ArgW) of Shewanella oneidensis contains 452aas with 10 putative TMSs in a 4+2+4 arrangement and N- and C- termini predicted inside. The Geobacillus homologue, HisW, contains 441aas with 10 or 11 putative TMSs; both N- and C- termini are inside. It is called the COG3314 family or GATE Superfamily (Rodionov et al., 2009).
The reaction believed to be catalyzed by ArgW is:
arginine (out) → arginine (in)
