Proposed subcellular localization, topology, and function of StoA in the intermembrane space of a forespore engulfed by the mother cell. The sporulation protein(s) (X) that requires disulfide bond reduction catalyzed by StoA and the electron donor (Y) to StoA remain to be identified. Thioredoxin (TrxA) in the mother-cell cytoplasm might be the donor of reducing equivalents to the electron donor and indirectly to StoA.
