The present invention provides a protein comprising the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3 (except for proteins of the amino acid sequences as shown in SEQ ID NOS: 4 to 6), and a process for industrially advantageously producing a compound that inhibits HMG-CoA reductase and has an action to decrease serum cholesterol, using DNA encoding the protein comprising the amino acid sequence as shown in any one of SEQ ID NOS: 1 to 3 (except for DNA encoding the protein comprising the amino acid sequence as shown in SEQ ID NO: 4).
