Descrizione generale

Glucose-6-Phophate Dehydrogenase (G-6-PDH) comprises His-Asp catalytic dyad and exists as a homodimer. Structurally, G-6-PDH encompasses a Rossmann dinucleotide binding fold in the coenzyme binding domain region. It also harbors a large β + α domain and has a unique aspartate residue at position 374.

Applicazioni

Glucose-6-phosphate Dehydrogenase from Leuconostoc mesenteroides has been used along with hexokinase in the determination of glucose from mice liver samples.

Azioni biochim/fisiol

Glucose-6-Phophate Dehydrogenase (G-6-PDH) can utilize either nicotinamide adenine dinucleotide phosphate (NADP+) or NAD+ as coenzyme making it crucial for bacterial metabolism.
Glucose-6-phosphate dehydrogenase (G6PD) catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.

Definizione di unità

One unit will oxidize 1.0 μmole of D-glucose 6-phosphate to 6-phospho-D-gluconate per min in the presence of NAD at pH 7.8 at 30 °C.
