Heterologous Expression of Production of T10, C12-CLA linoleic acid isomerase gene from Propionibacterium acnes

  The linoleic acid isomerase enzyme from Propionibacterium aches,which catalyzed the isomerization of a methylene-interrupted double bond system to a conjugated double bond system,creating trans-10,cis-12 conjugated linoleic acid (tl0,c12 CLA) was cloned and overexpressed in Escherichia coli using expression system of pCold-SUMO.The gene was expressed under T7 promotor with a fusion parmer of 6×His.Tag at its 5 terminal.After induction by 0.2mM IPTG for 18 h,the recombinant enzyme are expressing in the cytoplasm.The 1275 bp gene from P.acnes encode a linoleic acid isomerase protein with 424 amino acids (55KD).
