    • PROBLEM TO BE SOLVED: To provide an Aspergillus porphobilinogen synthase and an isolated nucleic acid fragment comprising nucleic acid sequence encoding the porphobilinogen synthase as well as a nucleic acid construct, a vector, and a recombinant host cell comprising the nucleic acid sequence and to provide a method of producing the porphobilinogen synthase. SOLUTION: The porphobilinogen synthase (a) has a specific amino acid sequence; or (b) has an amino acid sequence in which 1, 2 or 3 amino acids are inserted, removed or substituted in a specific amino acid sequence represented by sequence No. 2; or (c) is encoded by a nucleic acid sequence hybridizable under the same conditions by using a probe hybridized with a specific nucleic acid sequence under high stringent conditions.
