A maltogenic amylase gene, a recombinant molecule containing it, a transformant having the same, and an enzyme produced therefrom

摘要

The present invention relates to a maltose-producing amylase gene isolated from Bacillus stearothermophilus KCTC1044BP, which has a genetic map as shown in FIG. 1 and has a molecular weight of about 62000 Dalton as measured by 10% SDS-PAGE and isoelectric focusing (IEF ), The maltose-producing amylase produced by this gene acts on fluoran to produce mainly pannocose, decomposes starch to mainly produce maltose, and decomposes? -Cyclodextrin , And a maltogenic amylase gene. The present invention also relates to a recombinant molecule comprising said gene, a transformant having said recombinant molecule, and an enzyme produced therefrom.
