Abstract:
The present invention provides a novel dual-function lipase variant and its application in processing of flour products. The amino acid sequence of the lipase has one of the following amino acid substitutions: P298T, P298T/H317P, P298T/H317P/V326S, P298T/T218S/S234F, P298T/H317P/P168L/A129S, P298T/S234F/K161R/V326S or the nucleotide sequence of wherein said lipase is substituted, deleted, or added based on the sequence encoding the amino acid described in (a) and has at least 80% identity with it. The variants have good performance in processing of flour products, while they can significantly whiten the bread or other products in processing of flour products and significantly increase the specific volume in bread baking process.

Claim (Index 1):
A method of using a lipase mutant in processing of flour products,\n wherein the lipase mutant comprising: an amino acid sequence with substitutions selected from the group consisting of P298T, P298T/H317P, P298T/H317P/V326S, P298T/T218S/S234F, P298T/H317P/P168L/A129S, and P298T/S234F/K161R/V326S, wherein the substitutions are relative to a parent amino acid sequence set forth in SEQ ID NO:1; wherein the lipase mutant maintains a triglyceride and lecithin hydrolysis activity and good performance in thermostability; wherein the method comprises: expressing the lipase mutant from a culture of a recombinant yeast strain comprising an expression vector for the lipase mutant; preparing a purified form of the lipase mutant from the culture; adding a suitable amount of the purified form of the lipase mutant to a flour and water mix to obtain a product mix.
