CC   -!- FUNCTION: Inhibits the initiation of sporulation, Spo0J antagonizes
CC       this inhibition. Soj ultimately inhibits the activation
CC       (phosphorylation) of Spo0A. It is not required for chromosome
CC       partitioning (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216;
CC   -!- SIMILARITY: Belongs to the ParA family. {ECO:0000305}.
