Crystal structure of the complex of helicobacter pylori alpha-carbonic anhydrase with 5-amino-1,3,4-thiadiazole-2-sulfonamide inhibitor.
Warning
  • Chain breaks within knot 31 (displayed as a gray area on the plot and as '-' on the sequence). The broken part of the chain has been replaced by a straight segment, which may affect what knot types are detected - be careful with interpreting results.
