Figure 1. Trifunctional PCS: Structure and reaction sequence.

Figure 1

Dimeric structure of PCS from Erythrobacter sp. NAP1 (PDB 6EQO). One protomer is depicted in cartoon and one in surface representation. The multi-domain organization is highlighted by different colors: orange, ligase domain; purple, dehydratase domain; cyan, reductase domain; blue sphere, N-terminus; red sphere, C-terminus. Schematic arrangement of the three domains and their individual reactions are shown using the same color code.
