Aldolase, MP Biomedicals

Catalog Number: (ICNA0215985925)

Supplier: MP Biomedicals

Description: Aldolase is a tetrameric protein. It catalyses a key reaction in glycolysis and energy production:D-Fructose 1,6-bisphosphate aldolase → dihydroxyacetone phosphate + D-glyceraldehyde-3-phosphate. Aldolase is present in all animal tissue and in most microorganisms. There are two classes of aldolases. Class I aldolase is found in animal and higher plant tissue. Class II aldolase is found in primitrive cells such as yeasts and bacteria. Class I aldolase is characterised by not requiring a bivalent metal cofactor and the formation of a ketimine Schiff base intermediate with the substrate dihydroxyacetone phosphate. Class II aldolase requires a metal cofactor and is inhibited by EDTA. Three types of aldolase exist in animal tissue. The major form, type A is found in muscle; type B is found in liver tissue and type C (plus some type A) is found in brain tissue. Aldolase forms five isozymes which may to various degrees be organ specific.

Salmonella typhimurium (strain LT2/SGSC1412/ATCC 700720) recombinant tryptophan synthase (from E. coli)

Catalog Number: (PRSI92-668)

Supplier: ProSci Inc.

Description: Tryptophan synthase is a multienzyme alpha2 beta 2 complex composed of two protein subunit. Tryptophan synthase catalyses the last two steps in the synthesis of L-tryptophan (L-Trp). The alpha-subunit catalyses cleavage of 3-indole-d-glycerol 3′-phosphate (IGP) to give indole and D-glyceraldehyde 3′-phosphate (G3P). Indole is then transferred through a 25-Å hydrophobic tunnel to the beta -subunit. The beta 2 subunit contains pyridoxal 5'-phosphate and catalyses several pyridoxal 5'-phosphate-dependent reactions, including/3-elimination reactions 6 and a thiol-dependent transamination reaction. This enzyme is commonly found in Eubacteria, Archaebacteria, Protista, Fungi, and Plantae, but is absent from Animalia. As humans do not have tryptophan synthase, this enzyme has been explored as a potential drug target.
