Catalytically inactive. Belongs to the catalase family. Although a transcript has been detected, this protein has no catalase activity. Comparison with orthologs shows that the last 50 C-terminal amino acids, which seem to be essential for activity, are missing due to a natural frameshift in position 446. The sequence also contains six missense mutations, including the replacement of Pro-317 with Ser, which could modify the structure of the protein. Both alterations seem to contribute to the lack of catalase activity.
