A mutant alpha-amylase is provided that is the expression product of anmutated DNA sequence encoding an alpha-amylase, the mutated DNA beingnderived from a precursor alpha-amylase, which is a Bacillus alpha-amylase, bynsubstitution or deletion of an amino and at a position equivalent to M + 15 in Bnlicheniformis alpha-amylase. The mutant alpha-amylase are suitable for use inndetergent compositions and in process for starch liquification. |
