AB - Abstract 1) α-Amylases [EC 3. 2.1.1] from B. stearothermophilus grown at 55°c were separated into two isozymes. by chromatography on DEAE-cellulose. The major component showed greater thermostability than the minor one. 2) The properties of the two isozymes were compared with those of an α-amylase from the same bacterium grown at 43Cc. The α-amylase produced at 43°c was similar to the major component of the α-amylases produced at 55°c as regards various properties such as molecular weight, amino acid composition, electrophoretic properties, enzymatic properties, thermostability, and the pattern of circular dichroism. 3) The minor component produced at 55°c was probably not a proteolytic product derived from the major component during culture or purification.
