BamA has a C-terminal beta-barrel OM protein domain and an N-terminal periplasmic domain with five PORTA (polypeptide transport-associated) repeats that bind OM substrate peptides (Gatsos, 2008, Knowles, 2008; Ward, 2009). bamA is an essential gene. The ATG at codon 3 could be the true start codon. bamA is the last gene in the ispU-cdsA-rseP-bamA operon. HT_Cmplx49_Mem: DamX+BamA. ytfM and bamA are paralogs. An erroneous inner membrane localization may indicate binding to an inner membrane protein or cross-contamination (Lopez-Campistrous, 2005). otherPDB(H.ducreyi): 4K3C (Noinaj, 2014). otherPDB(N.gonorrhoeae): 4K3B (Noinaj, 2013).
