title: Cloning in Bacillus subtilis of an extremely thermostable alpha amylase: comparison with other cloned heatstable alpha amylases.
abstract: A heatstable alpha amylase gene was shotgun cloned from Bacillus licheniformis RPO1 into Bacillus subtilis. Restriction endonuclease analysis of the recombinant plasmid revealed a map which was identical to a previously cloned alpha amylase from B. licheniformis FDO2 and very similar to the restriction map of a high temperature amylase from Bacillus coagulans. The thermostability and temperature optimum of the cloned alpha amylase was measureably different from those of the previously reported cloned alpha amylases.
