Fig. 4From: Structural insights into acyl-ACP selective recognition by the Aeromonas hydrophila AHL synthase AhyICommon and unique structural characterization of six representative AHL signal synthases AhyI, EsaI, LasI, TofI, BjaI and RpaI. A Substrate-binding pocket showing the two cavities that accommodated acyl-donor and SAM. B Primary sequence alignment of these AHL synthases. Residues involved in the acyl-donor substrate preference were marked in red. The numbers indicate the AhyI residuesBack to article page
