ABSTRACT
Total RNA was extracted from human LAK cell, and a cDNA encoding mature peptide HMG-17 and its alpha helix domain was amplified by RT-PCR. The recombinant prokaryotic expression vector pGEX-1lambdaT-HMG-17 and pGEX-1lambdaT HMG-17alpha helix was constructed. Using affinity chromatography, thrombin cleaving and AU-PAGE elution, we obtained the purified HMG-17. Analyses of MIC, MEC and MBC indicated that HMG-17 and HMG-17alpha had strong antibacterial activity. MIC of the alpha-helic domain was almost the same as that of HMG17, suggesting that the alpha-helic structure would be essential for the antibacterial activity of HMG-17.
