Characteristics Study on Oyster Catalase and Tegillarca granosa Catalase

Abstract

Abstract: The characteristics of Oyster catalase and Tegillarca granosa catalase were compared.The results indicated that theirpolyacrylamide gel electrophoresis bands were shown at the same location,and their relative molecular quanlity were about 230kD.Both enzymes contained four subunits.The temperture affecting enzyme activity was the same.Both enzyme activities weredecreased obviously when the temperture was at 50℃.Both enzymes optimum pH swere from five to eight.But Oyster catalaseenzyme activities were decreased obviously in acid or alkali.

Key words: Oyster, Tegillarca granosa, Catalase
