[Objective]To clone Fur( Ferric uptake regulator protein) gene form Mycoplasma pneumoniae( Mp) and purify Fur protein. [Methods]The Mp Fur with its homologous proteins were analysed by Clustal Omega and the phylogenetic tree was constructed by MEGA6. 0. The Mp Fur was amplified by PCR and ligated p ET28 a vector to generate the p ET28a- Fur plasmid,which was transformed into E. coli BL21( DE3). The Fur protein was induced by IPTG and purified by Ni2 +- affinity chromatography. [Results]The results of sequen...
