Abstract:
PURPOSE: A method for preparing a peptide antigen with enhanced immunogenicity is provided to enhance antibody-producing efficiency. CONSTITUTION: A polypeptide contains an amino acid sequence with two or more tandem repeat LEDTQKH amino active sequences and additionally contains one or two praline between the repeat amino acid sequences. The polypeptide is linked to polystyrene or polylactic-glycolic acid polymers or bovine serum albumin(BSA) or ovalbumin. A vaccine composition contains: the polypeptide with two or more tandem repeat LEDTQKH amino active sequences; the polypeptide with LEDTQKH sequences and proline; the polypeptide linked by the polystyrene or polylactic-glycolic acid polymers or bovine serum albumin(BSA) or ovalbumin; a nucleic acid encoding one of polypeptides; and an antibody for one of the polypeptides.
Abstract:
PURPOSE: A method for preparing human metabolites of simvastatin or lovastatin using bacterial cytochrome p450 is provided to selectively produce metabolic protucts. CONSTITUTION: A composition for preparing human metabolites of simvastatin or lovastatin has: 47th amino acid arginin(R) of wild type CYP102A1, which is substituted with alanine, valine, leucine, isoleucine, proline, methionine, phenylalanine, or tryptopane; 87th amino acid, phenylalaine(F) which is substituted with alanine, valine, leucine, isoleucine, proline, methionine, or tryptopane; 143th amino acid, gluamic acid(E), which is substituted with glycine, serine, threonine, cysteine, tyrosine, asparagine, or glutamine; and 188th amino acid, leucine(L), which is substituted with glycine, serine, threonine, cysteine, tyrosine, asparagine, or glutamine.
