FIELD: chemistry.
SUBSTANCE: disclosed is isolated α-amylase from Bacillus sp. 195, which is a shortened form which ends with a residue 492, 504 or 509 SEQ ID NO:3, given in the description. Described is a detergent additive containing said α-amylase in amount of 0.02-200 mg per g of detergent additive. Said detergent additive can be presented in form of dust-free granulated material, micro-granulated material, stabilised liquid, gel or protected enzyme.
EFFECT: invention enables to obtain a modified enzyme with higher catalytic activity compared to the parent enzyme.
