PROBLEM TO BE SOLVED: To obtain a protein high affinity for an aromatic compound, improved in decomposition ability, useful for waste water treatment, by including a protein PpxR containing a specific amino acid sequence, etc. SOLUTION: This protein is protein PoxR having an amino acid sequence comprising amino acids 1-568 in the formula, protein PoxA having an amino acid sequence comprising amino acids 569-642, protein PoxB having an amino acid sequence comprising amino acids 643-973, protein PoxC having an amino acid sequence comprising amino acids 974-1063, protein PoxD, PoxE, PoxF, PoxG, PoxH or PoxI having a fixed amino acid sequence, or a protein modified by deletion of one to several amino acids and/or substitution with another amino acid in the amino acid sequence and has the same biological activity as that of the corresponding amino acid sequence. The protein is obtained by culturing a host transformed with a vector containing a gene encoding one or more proteins. |
