FIG. 5. Thermal denaturation of HI0607 and mutants monitored with circular dichroism at 222 nm.

FIG. 5

HI0607 active site mutants D103N (∇) and K67N (□) exhibit similar temperature-dependent denaturation profiles and melting temperatures (Tm = 327 K) as those observed for the wild-type enzyme (●). U, units.
