Lanthionine introduction into nukacin ISK-1 prepeptide by co-expression with modification enzyme NukM in Escherichia coli.
We demonstrated lanthionine introduction into hexa-histidine-tagged (His-tagged) nukacin ISK-1 prepeptide NukA by modification enzyme NukM in Escherichia coli. Co-expression of nukA and nukM,Expand
