General description

Glucose 6-phosphate dehydrogenase (G-6-P-DH) is a key regulatory enzyme in the first step of the pentose phosphate pathway. G-6-P-DH is a glycoprotein[1] with a molecular mass of 128 kDa (gel filtration).[2]

Application

Glucose-6-phosphate dehydrogenase is used to test ketose reductase activity in developing maize endosperm.[3]

Biochem/physiol Actions

Glucose-6-phosphate dehydrogenase catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway<<<17>>>.
Glucose-6-phosphate dehydrogenase catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.

Unit Definition

One unit will oxidize 1.0 μmole of D-glucose 6-phosphate to 6-phospho-D-gluconate per min in the presence of NADP at pH 7.4 at 25 °C.

Physical form

Lyophilized and essentially sulfate-free; contains approx. 20% sodium citrate based on dry weight

Mycobacteria spontaneously form surface-associated multicellular communities, called biofilms, which display resistance to a wide range of exogenous stresses. A causal relationship between biofilm formation and emergence of stress resistance is not known. Here, we report that activation of a nitrogen

A combination of biological control and host plant resistance would be desirable for optimally controlling the greenhouse whitefly, Trialeurodes vaporariorum in tomato crops. Whitefly settlement preference, oviposition, and survivorship were evaluated on ABL 10-4 and 'Moneymaker', two nearly-isogenic tomato lines

Protocols

To measure glucose-6-phosphate dehydrogenase activity, beta-nicotinamide adenine dinucleotide phosphate is used in a spectrophotometric rate determination assay at 340 nm.
