CC -!- FUNCTION: Has low D-mannonate dehydratase activity (in vitro),
CC suggesting that this is not a physiological substrate and that it has
CC no significant role in D-mannonate degradation in vivo. Has no
CC detectable activity with a panel of 70 other acid sugars (in vitro).
CC {ECO:0000269|PubMed:24697546}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-mannonate = 2-dehydro-3-deoxy-D-gluconate + H2O;
CC Xref=Rhea:RHEA:20097, ChEBI:CHEBI:15377, ChEBI:CHEBI:17767,
CC ChEBI:CHEBI:57990; EC=4.2.1.8;
CC Evidence={ECO:0000269|PubMed:24697546};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000269|PubMed:24697546};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000269|PubMed:24697546};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC Note=kcat is 0.02 sec(-1) with D-mannonate.
CC {ECO:0000269|PubMed:24697546};
CC -!- SIMILARITY: Belongs to the mandelate racemase/muconate lactonizing
CC enzyme family. GalD subfamily. {ECO:0000305}.
