In the original article, there was a mistake in the legend for Figure 2 as published. It described that “The acid residue-abundant segment of Glu25-Lys46 (Glu6-Lys27 in the processed protein base) in S. cohnii DSM 6307T is indicated by green box” at L2 –L3. The correct legend appears below.
Figure 2. Amino acid sequence alignment of membrane bound cytochrome c-550 from Evansella clarkii and other alkaliphilic and neutralophilic Bacillaceae. Asn (N)-rich segment, Asn (N)21-Asn (N)43 [Asn (N)4-Asn (N)26 in the processed protein base] in the E. clarkii cytochromes c is indicated by red box. The acid residue-abundant segment of Glu25-Lys46 (Glu6-Lys27 in the processed protein base) in S. cohnii DSM 6307T is indicated by red box. N-terminal amino acid residue in processed cytochrome c, [Cys (C)] is indicated by blue marker. The blue boxed sequences are heme sequences representing heme-binding site and axical ligands (H and M). Acidic and basic residues are indicated by blue and red letters. Although A. pseudofirmus OF4 is a facultative alkaliphile, the species A. pseudofirmus and the presented cytochrome c sequence are classified in obligate alkaliphile. Although Sporosarcina pasteurii is an obligate alkaliphile, its cytochrome c sequence is similar to those in the facultative alkaliphilic strains.
In the original article, there was a mistake in Table 2 as published. The unit for respiratory rate was incorrect. The corrected Table 2 appears below.
Table 2
| Growth rate (μmax)1 | Cytochrome c content (nmol ·mg−1)1 | ΔΨ (mV)1,2 | Respiratory rate (μmol ·O2 min−1 mg−1)2 | H+/O1 | Maximum ATP synthesis rate2 (nmol ·min−1 ·mg−1)2 | |
