Title:
ALPHA-AMYLASES WITH MUTATIONS THAT IMPROVE STABILITY IN THE PRESENCE OF CHELANTS
Document Type and Number:
WIPO Patent Application WO/2020/077331
Kind Code:
A3
Abstract:
Disclosed are variant α-amylases having mutations that improve enzyme stability in the presence of chelants, methods of designing such variants, and methods of use, of the resulting variants. The variant α-amylases are particularly useful, for use in cleaning and desizing composition that include significant amounts of chelants.
