ERAP2 activity is unaffected by octamer and shorter peptides, and ERAP1 long peptide digestion products (A); ERAP1 reaction products from previous long peptide substrates, digestions were performed for 32min. Recovery of long peptide digestion products longer than 9 amino acids (Red), 9-mers (Orange), or 8-mers (Yellow). The data are the mean of 3 experiments. (B); Time course of ERAP2 activity against R-AMC in presence or absence of an 11-mer (EIRRYQKSTEL), 8-mer(RYQKSTEL) and the 6-mer (QKSTEL).
