a Representative chromatograms of purified V. cholerae Δldt mutant sacculi treated with LdtA for varying times. The percentage of LD-crosslinking is indicated on the right. b Activity of V. cholerae LTs (MltA, MltB, MltD, MltG and Slt70) on substrates with different LD-crosslinking levels relative to the sacculi substrate with 0% LD-crosslinks. c Relative activity of V. cholerae LTs (MltA, MltB, MltD, MltG and Slt70) on V. cholerae wild-type (Vc WT) or Δldt mutant (Vc Δldt) sacculi. Activity is calculated relative to the Δldt sacculi substrate, with 0% LD-crosslinks. d Relative activity of V. cholerae LTs (MltA, MltB, MltD, MltG and Slt70) on Photobacterium damselae wild-type (Pd WT) or Δldt mutant (Pd Δldt) sacculi. Activity is calculated relative to the Δldt sacculi substrate, with 0% LD-crosslinks. All in vitro assays were performed in triplicate. Data are presented as mean values +/- standard deviation. Source data are provided as a Source Data file.
