Transport-related genome content of the four Buchnera strains BAp, BSg, BBp and BCc.

a: TCDB nomenclature (Transporter Classification Database): 1, Channels/Pores; 2, Electrochemical Potential-driven Transporters; 3, Primary Active Transporters; 4, Group Translocators; 8. Accessory Factors Involved in Transport; 9, Incompletely Characterized Transport Systems.b: TCDB identification of best hit (from E.coli or Enterobacteriaceae if available) with TC-Blast (BLAST expectation values are given in the exp hit column).c: Number of transmembrane domains predicted by HMMTOP [51] for alpha-helix and UniProt protein region description for transmembrane beta-strands (localisation: i, inner membrane; o, outer membrane; c, cytosolic; nd, not determined).d: Official Swiss-Prot Buchnera gene name (or E. coli closest homolog if no name given in the primary annotation).e: number of genes in the complex. Ψ: pseudogene, ns hit: not significant hit.
