Protein
Nicotinate dehydrogenase large molybdopterin subunit
Gene
ndhL
Organism
Eubacterium barkeri (Clostridium barkeri)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the hydroxylation of nicotinate to 6-hydroxynicotinate. Also active against 2-pyrazinecarboxylic acid, but inactive against other nicotinate analogs.1 Publication

Catalytic activityi

Nicotinate + H2O + NADP+ = 6-hydroxynicotinate + NADPH.1 Publication

Cofactori

Binds 1 hydroxyoxoselanylmolybdenum molybdopterin cytosine dinucleotide per heterotetramer. The cofactor is bound between the ndhL and ndhM subunits.2 Publications

Enzyme regulationi

Reversibly inactivated by selenide and sulfide. Not inhibited by cyanide.1 Publication

pH dependencei

Most stable at pH 8.0. Unstable at acidic pH values.1 Publication
