Effect of temperature on activity (a) and thermostability (b) of immobilized and free TTL mutant. The reaction mixture (pH 8.0) was composed of 100 mM Tris-HCl, 100 mM CNDE and 5 mM zinc acetate. Symbols: filled triangle, free TTL mutant; filled diamond, immobilized TTL mutant; filled square, immobilized TTL mutant at 50°C; filled circle, free TTL mutant at 50°C; square, immobilized TTL mutant at 35°C; circle, free TTL mutant at 35°C.
