We have over-expressed the cDNA encoding Zm-p60.1 in E. coli and subsequently purified the recombinant protein using a purification procedure (Zouhar et al., 1999, Verdoucq et al., 2003) which uses a phosphate buffer system, imidazole as eluent. This procedure has been successfully applied to purify the native protein, but attempts to purify His-tagged mutants were not successful. The presence of glycerol (a protection agent) in the elution solutions causes precipitation of some mutants, and protein denaturation occurred during hydrophobic column chromatography. We therefore had to completely revise the purification protocol. For purification of recombinant enzyme and its histidine mutant forms,"@en . "43210" .
