Abstract: PrTX-I, a non-catalytic and myotoxic Lys49-PLA2 from Bothrops pirajai venom has been crystallized alone and in complex with bromophenacyl bromide (BPB), α-tocopherol and α-tocopherol acetate inhibitors. These crystals have shown to diffract X-rays between 2.34 and 1.65 Å resolution. All complexes crystals are isomorphous and belong to the space group P21 whereas native PrTX-I crystals belong to the P3121.
