Figure 3. Three-dimensional comparisons of cap regions from bacterial HSL enzymes.

Figure 3

(A) Superposition of the cap regions of LpEst1 (yellow) and PestE from P. calidifontis (green), which has been chosen arbitrarily as a representative model of the predominant pattern (see the text). (B) Superposition of the cap region from BFAE (dark green) and that from PestE. (C) Superposition of cap regions from PestE (green), AFEST (cyan), EstE2 (grey), EstE5 (light brown), EstE7 (magenta), heroin esterase (pale green) and Sto-Est from (blue). All structures are represented as ribbon models.
