COLOR PLATE 2 (chapter 7)
Structure of the active site of S. aureus PBP2’ acyl enzyme complex with nitrocefin. The structure (78) is shown as ball and stick model with the protein overlaid by an electrostatic surface calculated using MOLOC.

COLOR PLATE 3 (chapter 7)
Location of point mutations of E. faecium PBP5 conferring β-lactam resistance. The alpha-carbon chain of the structure of the transpeptidase domain of the acyl enzyme complex (120) formed with benzylpenicillin is shown with the inhibitor and the side chains of the residues implicated in β-lactam resistance shown as ball and stick models.

COLOR PLATE 4 (chapter 11)
Folding of OXA-10 protein (1FOF) as a ribbon presentation, with OXA-10 numbering. Key residues in the active site and the omega loop are indicated.

COLOR PLATE 5 (chapter 11)
Conserved residues in OXA-10 (1FOF) (67Ser-Xxx-Xxx-Lys, 115Ser-Xxx-Val, and 205Lys-Xxx-Gly [OXA-10 numbering]).

COLOR PLATE 6 (chapter 11)
OXA-13 β-lactamase, acylated by meropenem. The structure is a closed form with a noncarboxylated lysine. A water molecule (the big ball) is positioned at the end of Lys73 (70 in OXA-13) at a position similar to that of the carboxylate, and is correctly positioned to be catalytic. Strong hydrogen bonds are represented as dashed lines. Residues are numbered using OXA-10 numbering.

COLOR PLATE 8 (chapter 15)
Three-dimensional structure of EmrE from E. coli (Protein Data Bank [PDB] code 2f2m). Monomers are represented as green and blue ribbons. A bound TPP molecule is shown in red, and black lines indicate a proposed position of the lipid bilayer.

COLOR PLATE 13 (chapter 20)
Proposed IntI excision through a single-stranded DNA substrate pathway based upon a previously proposed model by Mazen et al. The bottom strand of the integron element, produced by conjugation or transformation, folds upon itself to yield an active stem-loop substrate (step 1). Two IntI molecules bind each folded attC site to form an antiparallel recombination synapse (step 2). Here, the HJ intermediate requires cellular components in order to be resolved (steps 5 and 6). IntI molecules colored green or magenta are potentially active or nonactive for cleavage, respectively.
