The structure of PRCP. (A) Schematic diagram of the secondary structure of PRCP. The canonical α/β hydrolase fold is shown in blue and cyan, the SKS domain in magenta, and the M and N helices of the hydrolase insert domain in yellow. (B) Ribbon diagram of tertiary structure of PRCP. The Asp-His-Ser catalytic triad is shown in red. Glycans are shown in green.
