    HTLV-1 protease (HTLV-1 PR) is an aspartic protease which represents a promising drug target for the discovery of novel anti-HTLV-1 drugs. The X-ray structure of HTLV-1 PR in complex with the well-known and approved HIV-1 PR inhibitor Indinavir was determined at 2.40 Å resolution. In this contribution, we describe the first crystal structure in complex with a nonpeptidic inhibitor that accounts for rationalizing the rather moderate affinity of Indinavir against HTLV-1 PR and provides the basis for further structure-guided optimization strategies.
