Figure 1

The identical residues are indicated by boxes. The sequence of the peptide reported to be inhibitory on the enzyme activity is underlined. The sequence of the longest histidine-tagged recombinant HTLV-1 protease form is also provided, where the stabilizing mutations (L40I, C90A, C109A) are in italics.
