Figure 4.
Phage display sequences generated after cleavage by human gzms A and K after six rounds of selection. After the last round of selection, the released phages were collected for sequencing. The amino acid sequences are P-G-G-?-?-?-?-?-?-?-?-?-H-H-H-H-H-H and the “?” means randomized amino acids. The amino acid sequences were aligned into a P5-P4’ consensus. The cleavage occurs between positions P1 and P1’. The classification of amino acids was indicated by color based on the side chain properties located in the right bottom corner of the figure. In (A) we show the results for gzm A and in (B) for gzm K Web Logo presentations of the target selectivity of human gzms A and K are displayed in (C, D), respectively.
