TRANSKETOLASE FROM ESCHERICHIA COLITRANSKETOLASE FROM ESCHERICHIA COLI

Structural highlights

1qgd is a 2 chain structure with sequence from "bacillus_coli"_migula_1895 "bacillus coli" migula 1895. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:, ,
Activity:Transketolase, with EC number 2.2.1.1
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[TKT1_ECOLI] Catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose-5-phosphate. Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.[1]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
