PMID: 17573533
Chloroplast glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a light-regulated, NAD(P)H-dependent enzyme involved in plant photosynthetic carbon reduction. Unlike lower photosynthetic organisms, which only contain A(4)-GAPDH, the major GAPDH isoform of land plants...

PMID: 11846565
Here, we report the first crystal structure of a photosynthetic glyceraldehyde-3-phosphate dehydrogenase (GAPDH) complexed with NADP. The enzyme, purified from spinach chloroplasts, is constituted of a single type of subunit...

FEBS Lett
. 1999 Dec;
463(3):382-6.
PMID: 10606758
In higher plants, NAD(P)H:quinone reductase (NQR) is the only flavoreductase known to reduce quinone substrates directly to hydroquinones by a two-electron reaction mechanism. This enzymatic activity is believed to protect...

Arch Biochem Biophys
. 1999 Mar;
363(2):301-8.
PMID: 10068452
A novel NADH-dependent, soluble flavoreductase of 60 kDa, active toward ferric chelates and quinones, has been purified from maize seedlings. Two closely related isoforms were separated. The two isoforms are...

PMID: 9323038
Microsomal NADH:Fe(III)-chelate reductase (NFR) of maize roots has been purified as a monomeric flavoprotein of 32 kDa with non-covalently bound FAD. In the presence of NADH, NFR efficiently reduced the...
