BIOLOGICALLY THE PROTEASE DOMAIN FUNCTIONS AS PART OF THE LARGER (631 RESIDUE) PROTEIN. THE LARGER PROTEIN HAS NOT BEEN SHOWN TO EXIST AS A DIMER. THE SMALLER PROTEASE DOMAIN (RESIDUES 1-181) THAT HAVE BEEN EXPRESSED WITH AN N-TERMINAL T7 EPITOPE TAG AND A C-TERMINAL HIS TAG, EXISTS AS A DIMER IN THE ASYMMETRIC UNIT. IT IS UNKNOWN WHETHER THIS PROTEIN DOMAIN IS FUNCTIONAL AS A MONOMER OR A DIMER.
The asymmetric unit contains a dimer of the protease domain which is the N-terminal 181 residues of the NS3 protein (631 residues) that contains both the protease domain and the helicase domain. Biological the protease domain functions as part of the larger (631 residue) protein. The larger protein has not been shown to exist as a dimer. The smaller protease domain (residues 1-181) that have been expressed with an N-terminal T7 epitope tag and a C-terminal His Tag, exists as a dimer in the asymmetric unit. This protein domain is believed to be functional as either a monomer or a dimer.

The trays were set at 4C for 5-7 days to control nucleation, followed by incubation for 3 weeks at 12C to maximize crystal growth. , pH 5.7, VAPOR DIFFUSION, HANGING DROP, temperature 285K
