3.A.1.125.7
ABC-type transport system, possibly involved in lipoprotein release. There are two and possibly three protein constituents. First, there is a permease component of 1004 aas with 13 TMSs in a 2 (N-terminal) + 3 +4 + 1 + 3 TMS arrangement (I2F7A7)).  This protein is unusual because it has 2 N-terminal TMSs rather than the usual 1, and between the two 1 + 3 TMS repeat units, there are 4 TMSs rather than the more usual 0 or 2 TMSs. Second, there is an ABC-type ATPase (I2F7A6) and third, there is a possible auxiliary subunit of 183 aas and 4 TMSs in a 2 + 2 TMS arrangement that appears to be two repeated 2 TMS sequences, one near the N-terminus and one near the C-terminus; I2F7A5).  Adjacent to these genes is one annotated as a "PRC barrel protein" (with a single N-terminal TMS and is a conserved, ubiquitous, chromo domain, shared by photosynthetic reaction center subunits and proteins of RNA metabolism (Anantharaman and Aravind 2002); I2F7A4) of unknown function, and adjacent to that gene are two genes encoding putative chromate resistance efflux (transport) protein, ChrA (I2F7A3 and I2F7A1; see TC family 2.A.51).
