Patent ID: 8252562

Claim:
An enzyme powder comprising a spray-dried formulation of a) at least one enzyme structurally classified as a CE-7 enzyme and having perhydrolysis activity and a signature motif comprising: i) an RGQ motif at amino acid residues 118-120, ii) a GXSQG motif at residues 179-183, and iii) an HE motif at residues 298-299 when aligned to reference sequence SEQ ID NO:1 using CLUSTALW, said enzyme further having at least 30% amino acid identity to SEQ ID NO:1; b) at least one oligosaccharide excipient; and c) optionally at least one surfactant; wherein said at least one oligosaccharide excipient stabilizes the perhydrolysis activity of said at least one enzyme when present in a formulation comprised of a carboxylic acid ester and the enzyme powder.
