Extracellular alkaline protease was purified from A. nidulans in a dance procedure involving ammonium sulfate precipitation and Sephadex G-100 column chromatography. The molecular(a) aggregated of the enzyme was determined to be 42 kDa by SDS-PAGE. The enzyme military action was overly study by zymogram with gelatin. The enzyme was more inactive over a large-minded range of pH (610) and the temperatures up to 50 °C. It showed best enzyme activity at pH 8.0 and a temperature of 35 °C.

The protease enzyme was entirely inhibited by the serine protease inhibitor of phenylmethylsulfonyl fluoride (PMSF). The crystallization of the purified enzyme was performed by reprieve falloff vapour diffusion regularity using pin roll 6000 as the precipitant. The micro crystals occurred in 40% of PEG 6000.

They ar the close to important industrial enzymes accounting system for about 60% of the extreme enzyme marketplace [2].
