The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
Prostate specific Antigen (PSA, KLK3) cleaves IGFBP-3 in the IGF:IGFBP-3:ALS Complex between amino acids 186 and 187. Other cleavage sites were observed but not reproducibly. These may have been caused by impurities in the PSA preparation.
