Aldolase B Protein, Human (N-GST)

Aldolase B protein catalyzes fructose 1,6-bisphosphate to trisaccharide phosphate during glycolysis and performs reverse aldol addition during gluconeogenesis. Aldolase B Protein, Human (N-GST) is the recombinant human-derived Aldolase B protein, expressed by E. coli , with N-GST labeled tag. The total length of Aldolase B Protein, Human (N-GST) is 363 a.a., with molecular weight of ~60 kDa.

Aldolase B protein serves a pivotal role in glycolysis by catalyzing the aldol cleavage of fructose 1,6-bisphosphate into dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate, as well as the reverse stereospecific aldol addition reaction in gluconeogenesis. Additionally, in fructolysis, it metabolizes fructose 1-phosphate, derived from the phosphorylation of dietary fructose by fructokinase, into dihydroxyacetone phosphate and D-glyceraldehyde. Beyond its enzymatic function, Aldolase B acts as an adapter and functions as a tumor suppressor by stabilizing a ternary complex with G6PD and TP53, inhibiting G6PD activity. This regulatory mechanism helps maintain control over oxidative pentose phosphate metabolism, contributing to the overall balance of cellular metabolic pathways.

Measured by its ability to catalyzes the decomposition of fructose 1,6 bisphosphate in the presence of NADH. The specific activity is 4.1 U/mg.

Lyophilized from a 0.2 μm solution of PBS, pH 7.4

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in sterile distilled water. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
