Amino acid sequence of B. subtilis GerAA protein. An alignment was generated using 10 proteins: B. subtilis GerBA (NP_391461), GerKA (NP_388252), YndD (NP_389658), YfkQ (NP_388660), B. cereus GerLA (NP_977103), GerIA (AAD03541), B. anthracis GerAA (NP_845469), B. thuringiensis GerAA (YP_037228), and Clostridium tetani GerAA (NP_780991) from the NCBI Protein Database. An asterisk above the position indicates that the residue was identical in all. Predicted transmembrane regions (by TOPCONS [4], including the sequences of confirmed functional GerAA homologs GerAA, GerBA, and GerKA from B. subtilis and GerLA, GerXA, GerHA, and GerSA from B. anthracis) are shown as black lines above the sequence. Amino acid substitutions in gerAA mutants are indicated by single underline (random mutations) and double underlines (site-directed mutations). A summary of the effects of the changes is shown in Table 1.
