Interactions of 7-ACA derivative with the active site of wild type TEM-1 β-lactamase (PDB code: 1XPB). The poses with the lowest docking score are represented for: a) 7-ACA derivative (3R,4S), ring A reactive; b) 7-ACA derivative (3R,4S), ring B reactive; c) 7-ACA derivative (3S,4R), ring A reactive; d) 7-ACA derivative (3S,4R), ring B reactive. The 7-ACA derivative is represented in stick mode. The residues at a distance of less than 5 Å are represented as lines and labelled. The color code is: carbon green, oxygen red, nitrogen blue, sulphur yellow. Hydrogens are not shown. See Additional file 1: Table S1 for further details
