2. SPECIFIC ACTIVITY

2.5 U/mg protein (on pNP-α-araf) at pH 7.0 and 37℃

One Unit of pNP-α-Araf activity is defined as the amount of enzyme required to release 1 μmol of p-nitrophenyl per minute from pNP-α-Araf (5 mM) in phosphate buffer (20 mM) pH 7.0.

3. RELATIVE RATES OF HYDROLYSIS OF SUBSTRATES
