the enzyme has a relatively narrow optimum around pH 8.0. In standard assay conditions, the enzyme activity declines precipitously at lower pH, dropping to 20% around pH 7.4 and becoming practically negligible below pH 7.0. The enzyme activity also declines substantially but more gradually, losing around 50% at pH 9.0. The enzyme exhibits significant activity at pH 6.5 in the presence of Mn2+, Co2+, Zn2+, Fe2+ and Ni2+ |
