Transketolase is highly specific for ketol donor substrates and is stereospecific and enantioselective to hydroxyaldehyde substrates with an (R) configuration. It specifically catalyzes the irreversible transfer of one ketol unit from α-hydroxypyruvic acid to an aldehyde to produce a D-threo (3S,4R)ketose.
Transketolase, Native (Thermophillic bacteria)
This enzyme is a potential candidate for biocatalysis, suitable for pharmaceutical development / manufacturing. Asymmetric C-C bond formation, ketol donor D-xylulose-5-phosphate may be substituted by hydroxypyruvate; preparation of ketose sugars such as fructose analogs, azasugars and fluorogenic substrates.
