The gene encoding a thermostable amidase (EC 3.5.1.4) from thermophilic bacterium Thermus sp.O-3-1, was cloned and expressed in Escherichia coli JM109. The cloned amidase gene (ami) is 930 bp and encodes a protein composed of 310 amino acids. The protein is predicted to have a molecular mass of 33,089 Da. The amidase from Thermus sp.O-3-1 was purified by heat treatment and DEAE Toyopearl 650M column chromatography. The molecular mass of the native enzyme was estimated to be about 70 kDa by gel filtration chromatography, indicating that the enzyme has a homodimeric structure. The purified enzyme was stable up to 80°C and within a pH range from 7.0 to 10.0. The optimum temperature and pH for enzyme activity were 90°C, and 9.0, respectively. T...
