6.3.2.9 - 1298, 1302, 1305, 675446 6.3.2.9 method that includes chromatography by a Talon resin 651400 6.3.2.9 method that includes DEAE-Trisacryl M and hydroxyapatite-Ultrogel chromatography. Large-scale purification using 2-mercaptoethanol as a reducing agent, results in 200 mg of purified enzyme from 54 l of culture, adducts with one or two molecules of 2-mercaptoethanol are formed. Replacement of 2-mercaptoethanol by dithiothreitol gave 162 mg of enzyme from 36 l of culture yielding no clusters with the reducing agent. 653712 6.3.2.9 recombinant His6-tagged enzyme from Escherichia coli strain DH5alpha by nickel affinity chromatography and dialysis 746203 6.3.2.9 recombinant protein 714367 6.3.2.9 recombinant recombinant GST-tagged MurD from Escherichia coli by glutathione affinity chromatography, His-tagged MurD from Mycobacterium smegmatis by nickel affinity chromatography 690835
