Isoelectric point profiles, calculated at 0.2 intervals, of predicted proteins encoded by the genomes of the three fermentative halophilic anaerobes: Halanaerobium praevalens GSL^T (2,110 proteins; median pI 7.42), the thermophilic Halothermothrix orenii H168^T (2,365 proteins, median pI 7.41) and the alkaliphilic and thermophilic Natranaerobius thermophilus JW.NM-WN-LF^T (2,906 proteins; median pI 6.27). From the genome annotations (Mavromatis et al., 2009; Ivanova et al., 2011; Zhao et al., 2011) sequences encoding proteins or putative proteins were extracted, and pI profiles were calculated as for Figure 1.
