Comments [?]

case <OC:Halobacteria>
Function Catalyzes the NAD(P)(+)-dependent oxidation of D-glucose to D-gluconate via gluconolactone. Can utilize both NAD(+) and NADP(+) as electron acceptor. Is involved in the degradation of glucose through a modified Entner-Doudoroff pathway.
else
Function Catalyzes the NAD(P)(+)-dependent oxidation of D-glucose to D-gluconate via gluconolactone. Can utilize both NAD(+) and NADP(+) as electron acceptor. Is involved in the degradation of glucose through a non-phosphorylative variant of the Entner-Doudoroff pathway.
end case
Catalytic activity RHEA:14293: D-glucose + NAD(+) = D-glucono-1,5-lactone + H(+) + NADH
EC 1.1.1.47
RHEA:14405: D-glucose + NADP(+) = D-glucono-1,5-lactone + H(+) + NADPH
EC 1.1.1.47
case <FTGroup:1> and <FTGroup:2>
Cofactor Zn(2+)
Note: Binds 2 Zn(2+) ions per subunit. One of the zinc atoms is essential for catalytic activity while the other has a structural function.
else
Cofactor Zn(2+)
end case
Similarity Belongs to the zinc-containing alcohol dehydrogenase family. Glucose 1-dehydrogenase subfamily.

Fusion None
Comments Some members of this family also display good catalytic efficiency with D-galactose as substrate (SULSF, Q6L047 in PICTO, THEAC), which seems to be a physiological substrate in some species.
