Abstract:
A method for crystallization of activated human AMPK alpha 1 domain is provided to clarify new obesity, diabetes and crystalline structure of human AMP kinase protein which is anti-cancer target protein. A method for crystallization of activated human AMPK alpha 1 domain comprises steps of: including human AMPK alpha 1 domain solution within buffer solution mixing glycerol, ATP and DTT in solution in a water tank including polyethylene glycol and tris buffer solution; and crystallizing it by a hanging-drop vapor diffusion method. The activated human AMPK alpha 1 domain is a composite of ATP, phosphate group and glycerol molecule. The hanging-drop vapor diffusion method is performed in 4~30°C and pH 7.0~ 7.5.
Abstract:
The present invention relates to a method for screening cancer therapeutic agents using modified arginyl tRNA synthetase (RARS) and, more specifically, to modified RARS represented by amino acid of sequence number 4 in which 72 amino acids are removed from N terminal of human RARS, and to a method for screening cancer therapeutic agents using amino acid residue position to which the protein and L-canavanine are combined. The present invention is effective for screening a substance which can be a competitive inhibitor against arginine as the canavanine using the amino acid residue of the modified RARS combined with the canavanine. In other words, the present invention is effective for screening the cancer therapeutic agent.

Abstract:
PURPOSE: An anti-herpesviral pharmaceutical composition containing oxonaphthalene-based compounds is provided to effectively prevent or treat diseases or disorders caused by herpesvirus without drug toxicity or drug resistance. CONSTITUTION: An anti-herpesviral pharmaceutical composition contains oxonaphthalene-based compounds of chemical formula 3 or 4 which suppresses herpesvirus exonuclease activity or a pharmaceutically acceptable salt as an active ingredient. The composition has an antiviral activity against gamma-herpesvirus such as Epstein-Barr Virus(EBV) or Kaposi's sarcoma associated virus(KSHV). The concentration of the compound is 1-100 uM.
Abstract:
The present invention relates to a crystal structure of modified EPR protein and a crystallization method thereof and, more specifically, to a method which overexpresses the modified EPR protein where 1000 number of amino acids are removed from the N end portion of bifunctional glutamate/proline tRNA synthetase (EPRS) protein derived from human and refines and crystallizes the protein, and a crystal structure analyzed thereby. Therefore, the present invention provides the crystal structure and crystallization method of modified EPR protein having an amino acid of sequence number 1 including a PRS protein domain portion of the EPRS protein derived from human and can be used for inhibitor development.
