CC   -!- FUNCTION: Catalyzes the NADP(+)-dependent oxidation of succinate
CC       semialdehyde to succinate. Although it has succinate semialdehyde
CC       dehydrogenase activity, is likely to act physiologically on a different
CC       aldehyde(s) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=succinate semialdehyde + NADP(+) + H2O = succinate + NADPH + 2
CC         H(+); Xref=Rhea:RHEA:13213, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30031, ChEBI:CHEBI:57706, ChEBI:CHEBI:57783,
CC         ChEBI:CHEBI:58349; EC=1.2.1.79;
CC   -!- SIMILARITY: Belongs to the aldehyde dehydrogenase family.
CC       {ECO:0000305}.
