KEGG ENZYME: 1.4.1.24

ENZYME: 1.4.1.24

Entry

EC 1.4.1.24                 Enzyme

Name

3-dehydroquinate synthase II;
DHQ synthase II;
MJ1249 (gene name);
aroB' (gene name)

Class

Oxidoreductases;
Acting on the CH-NH2 group of donors;
With NAD+ or NADP+ as acceptor

Sysname

2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate:NAD+ oxidoreductase (deaminating)

Reaction(IUBMB)

2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate + H2O + NAD+ = 3-dehydroquinate + NH3 + NADH + H+ [RN:R08569]

Reaction(KEGG)

R08569

Substrate

2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate;
H2O [CPD:C00001];
NAD+ [CPD:C00003]

Product

3-dehydroquinate [CPD:C00944];
NH3 [CPD:C00014];
NADH [CPD:C00004];
H+ [CPD:C00080]

Comment

The enzyme, which was isolated from the archaeon Methanocaldococcus jannaschii, plays a key role in an alternative pathway for the biosynthesis of 3-dehydroquinate (DHQ), an intermediate of the canonical pathway for the biosynthesis of aromatic amino acids. The enzyme catalyses a two-step reaction - an oxidative deamination, followed by cyclization.
