CC   -!- FUNCTION: Controls heterocyst differentiation. Dimerization is required
CC       for DNA-binding. Has both a protease and a DNA-binding activity.
else
CC   -!- FUNCTION: Might be involved in temporal and/or spatial regulation of
CC       nitrogen fixation. Dimerization is required for DNA-binding. Has both a
CC       protease and a DNA-binding activity.
end case
CC   -!- SUBUNIT: Homodimer; disulfide-linked.
CC   -!- SIMILARITY: Belongs to the peptidase S48 family.
