Glucose 1-dehydrogenase
In enzymology, a glucose 1-dehydrogenase (EC 1.1.1.47) is an enzyme that catalyzes the chemical reaction
- beta-D-glucose + NAD(P)+ D-glucono-1,5-lactone + NAD(P)H + H+

The 3 substrates of this enzyme are beta-D-glucose, NAD+, and NADP+, whereas its 4 products are D-glucono-1,5-lactone, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is beta-D-glucose:NAD(P)+ 1-oxidoreductase. Another name in common use is D-glucose dehydrogenase (NAD(P)+).
Structural studies
As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes 1G6K, 1GCO, 1GEE, 1RWB, 1SPX, 2B5V, 2B5W, 2CD9, and 2CDA.
gollark: I wonder how hard/expensive it'd be to run your own channel on the satellite system if there are THAT many.
gollark: We have exciting TV like "BBC Parliament".
gollark: Analog TV got shut down here ages ago.
gollark: So I guess if you consider license costs our terrestrial TV is *not* free and costs a bit more than Netflix and stuff. Oops.
gollark: - it funds the BBC, but you have to pay it if you watch *any* live TV, or watch BBC content online- it's per property, not per person, so if you have a license, and go somewhere without a license, and watch TV on some of your stuff, you are breaking the law (unless your thing is running entirely on battery power and not mains-connected?)- it costs about twice as much as online subscription service things- there are still black and white licenses which cost a third of the priceBut the enforcement of it is even weirder than that:- there are "TV detector vans". The BBC refuses to explain how they actually work in much detail. With modern TVs I don't think this is actually possible, and they probably can't detect iPlayer use, unless you're stupid enough to sign up with your postcode (they started requiring accounts some years ago).- enforcement is apparently done by some organization with almost no actual legal power (they can visit you and complain, but not *do* anything without a search warrant, which is hard to get)- so they make up for it by sending threatening and misleading letters to try and get people to pay money
