    Abstract: Mutated α-amylases having a sequence derived from the sequence of the liquefied alkaline α-amylase represented by SEQ ID NO:1 by, at least, deletion or substitution by another arbitrary amino acid residue of the methionine residue at the 202-position or a position homologous thereto; and detergent compositions containing the same. These mutated α-amylases have the optimum pH value in the alkaline region, an excellent α-amylase activity and a high and sustained tolerance against oxidizing agents. These properties make them useful as a component of detergent compositions containing, in particular, bleaching agents and oxidizing agents.

    Abstract: A liquefying alkaline alpha -amylase having the following enzymological properties: (1) action: this enzyme hydrolyzes alpha -1,4-glycoside linkages of starch, amylose, amylopectin and partial hydrolyzates thereof, and forms glucose, maltose, maltotriose, maltotetraose, maltopentaose and maltohexaose from amylose, though it does not act upon pullulan; (2) isoelectric point: it has an isolectric point exceeding 8.5 as measured by isoelectric electrophoresis. This enzyme has such a liquefying activity as to hydrolyze starch and starch polysaccharides at high random and has an optimum pH value on an alkaline side. Since it has a high isoelectric point, it can readily be purified. A detergent composition containing this enzyme has an excellent detergency against especially stains due to spilt food.

    Abstract: The present invention relates to a novel enzyme called alkaline proteinase K-16 that is characterized as having an optimum pH in an alkaline range, and stability in the presence of various surface active agents, such as sodium linear alkylbenzene sulfonate, sodium polyoxyethylene alkyl sulfate, sodium dodecyl sulfate, sodium alpha -olefin sulfonate, sodium alkyl sulfonate, and alpha -sulfo-fatty acid ester. The present invention further provides for a microorganism producing the novel alkaline proteinase, and a process for producing the novel alkaline proteinase. Alkaline proteinase K-16 of the present invention exhibits an excellent action against insoluble proteins and maintains sufficient activity over a wide temperature range and in the presence of surface active agents thus providing a use as an enzyme for detergents.
