Similar to TatB, TatE has conserved N-terminal charges. (A) Sequence alignment of the amino acid sequences of E. coli TatE (accession number: P0A843), TatB (P69425) and TatA (P69428). N-terminal, charged amino acid residues of TatE and TatB are highlighted in red, other charged residues are in bold. Secondary structural elements are assigned according to the NMR structure of TatAd from B. subtilis9 based on the multiple sequence alignment to its E. coli homologues (see Fig. 5B). (B) Consensus sequence of TatE obtained from the alignment of 111 distinct TatE protein sequences encoded by members of the Family of Enterobacterales. The N-terminal charged amino acids are boxed and their degree of conservation is indicated.
