Figure 2From: A probable aculeacin A acylase from the Ralstonia solanacearum GMI1000 is N-acyl-homoserine lactone acylase with quorum-quenching activitySDS-PAGE analysis Aac expressed by E. coli BL21(DE3). The crude proteins were prepared from the recombinant E. coli BL21 (pET21aac) and analysed by 6% SDS-PAGE. The arrow indicates the Aac. Lane 1, pre-stained protein ladder marker; lane 2, IPTG-induced crude proteins; lane 3, IPTG-non-induced crude proteins.Back to article page
