THE NS3 PROTEIN (1MG/ML) WAS INCUBATE AT 4C WITH THE NS4A COFACTOR PEPTIDE, CONTAINING A SOLUBIZING LYSINE TAG AT ITS N- AND C-TERMINI(KGSVVIVGRIILSGRK), AT A MOLAR RATIO OF 1:2 AND CONCENTRATED TO 290 MICROMOLAR. NS3J/4A CRYSTAL WITH A MAXIMUM SIZE OF 0.6 X 0.3 X 0.2 MM**3, WERE OBTAINED BY BOTH HANGING- AND SITTING-DROP VAPOUR DIFFUSION METHODS AFTER TW WEEKS AT ROOM TEMPERATURE, WITH 3.4 M NACL, 10MM DTT, 0.1 M CITR BUFFER PH 5.1. THE TERNARY COMPLEX WITH INHIBITOR WAS PREPARED B ADDING 2.5 MM OF INIBITOR TO CRYSTALS THAT WERE STABILISED IN 4.5 M NACL, 10 MM DTT, 0.1 M CITRATE BUFFER, PH 5.1., VAPOR DIFFUSION, SITTING DROP, TEMPERATURE 277K |
