Figure 1From: What you should know about PR3-ANCA: Structural aspects of antibodies to proteinase 3 (PR3)Stereogram α -carbon representation of PR3 and trypsinogen, showing carbon trace backbone in yellow, color-coded to indicate the B factors of trypsinogen from yellow (low B factor) to red (high B factors). Antigenic sites identified as linear regions located at the N-terminal regions of the molecule are shown as blue lines. Reproduced with permission from [14*].Back to article page
