Prediction of TMDs of EscV. (A) TMHMM software prediction analysis of the probability of each EscV amino acid to be localized within the bacterial membrane. Seven TMDs were identified (sequence is colored red). (B) Sequence alignment of the EscV export apparatus protein. A standard protein BLAST alignment is presented by ClustalW (Larkin et al., 2007) for EscV of EPEC T3SS (B7UMA7), FlhA of E. coli flagella (P76298), EscV of the E. coli O157:H7 (Q7DB70), YscV of the Y. enterocolitica (A0A2J9SJU1), MxiA of the Shigella T3SS (P0A1I5), and InvA of the S. typhimurium T3SS (A0A0H3NL68). A high level of conservation was observed within the TMD6 sequence and for the GxxxG motif found within TMD5.
