3.A.1.5.46
Putative oligopeptide transporter, OppA1A2BCDF. The two membrane proteins (OppB and OppC, of 564 and 670 aas with 13 and 15 TMSs, respectively (M-subunits)) and the two ATPases (C-subunits of 342 and 369 aas, respectively) map together, but the 4 potential receptors (R) map elsewhere on the chromosome. Two of them appear to be complete and have 734 and 738 aas, respectively, each with 2 TMSs, one N-terminal and one C-terminal.  There are two other potential receptors that may not have complete sequences.  They are OLS21443 (721 aas with only 1 C-terminal TMS) and OLS22122 (353 aas with only 1 N-terminal TMS).
