Characterization of ANS1/2-R3 pronase digestion products with altered retention times following chondroitinase ABC digestion. RP-HPLC chromatograms (Abs²³⁰ v. min) ANS1/2R3Pr1-d, -h, -i, -j, and -p following chondroitinase ABC digestion. Arrows indicate retention times of the main peak prior to chondroitinase ABC digestion. N-terminal sequences determined for the contents of each labeled peak (D, H, I, J1, J2, P1 and P2) are shown on the lower right. Blank cycles, indicated by an "x", identified Ser²³⁸ and Ser²⁵⁰ as modified residues.
