GerBA in outgrowing spores. P100 fractions from outgrowing (10 OD₆₀₀ units) spores of strains FB60 (ΔgerB; lane A) and PS832 (wild type; lane B) prepared as described in Materials and Methods were run on an SDS-PAGE gel, proteins were transferred to an Immobilon membrane, and GerBA was detected as described in Materials and Methods. Arrowheads labeled I and II denote GerBA bands in regions I and II, respectively, and background bands and molecular mass markers are labeled as in Fig. 2.
