CC -!- FUNCTION: 2,5-dioxopentanoate dehydrogenase involved in the degradation
CC of pentoses such as D-arabinose or D-xylose, a major component of
CC hemicelluloses such as xylan. Catalyzes the fifth reaction in the
CC pentose utilization pathway through dehydratation of 2,5-
CC dioxopentanoate into 2-oxoglutarate. Shows also dehydrogenase activity
CC toward glycolaldehyde and DL-glyceraldehyde.
CC {ECO:0000269|PubMed:16849334}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2,5-dioxopentanoate + H2O + NADP(+) = 2-oxoglutarate + 2 H(+)
CC + NADPH; Xref=Rhea:RHEA:11296, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC ChEBI:CHEBI:58349; EC=1.2.1.26;
CC Evidence={ECO:0000269|PubMed:16849334};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 7.8. {ECO:0000269|PubMed:16849334};
CC -!- SUBUNIT: Homotetramer. {ECO:0000269|PubMed:16849334}.
CC -!- INDUCTION: Expression is highly induced during growth on D-arabinose.
CC The promoter contains the conserved cis-regulatory element 5'-AACATGTT-
CC 3' ARA-box found in arabinose-induced genes.
CC {ECO:0000269|PubMed:16849334}.
CC -!- SIMILARITY: Belongs to the aldehyde dehydrogenase family.
CC {ECO:0000305}.
