Detergent composition comprising a DNase
The present invention relates to new polypeptides, nucleotides encoding the polypeptide, as well as methods of producing the polypeptides. The present invention also relates to detergent composition comprising polypeptides, a laundering method and the use of polypeptides.
1. A detergent composition comprising a polypeptide having DNase activity, wherein the polypeptide comprises the motif [G/Y/W/F/A/H]NI[R/Q/D/E/V] (SEQ ID NO: 73) or SDH[D/H/L]P (SEQ ID NO: 74), and
a surfactant selected from the group consisting of anionic and nonionic surfactants,
wherein the polypeptide having DNase activity has at least 90% sequence identity to the polypeptide of SEQ ID NO: 6, or is a fragment thereof having DNase activity.
2. The detergent composition of claim 1 , wherein the polypeptide having DNase activity comprises the motifs [G/Y/W/F/A/H]NI[R/Q/D/E/V] (SEQ ID NO: 73) and SDH[D/H/L]P (SEQ ID NO: 74).
3. The detergent composition of claim 1 , wherein the polypeptide having DNase activity further comprises the motif GGNI[R/Q] (SEQ ID NO: 75).
4. The detergent composition of claim 1 , wherein the polypeptide having DNase activity has at least 95% sequence identity to the polypeptide of SEQ ID NO: 6.
5. The detergent composition of claim 1 , wherein the polypeptide having DNase activity is the polypeptide of SEQ ID NO: 6.
6. The detergent composition of claim 1 , further comprising at least one additional component selected from the group consisting of
(a) a polyol,
(b) an enzyme selected from the group consisting of amylases, lipases, and proteases, and
(c) one or more polymers.
7. The detergent composition of claim 1 , wherein the surfactant is selected from the group consisting of soap, LAS, AEOS and SLES.
8. The detergent composition of claim 6 , wherein the polymer is selected from the group consisting of (carboxymethyl)cellulose (CMC), poly(vinyl alcohol) (PVA), poly(vinylpyrrolidone) (PVP), poly(ethyleneglycol) and poly(ethylene oxide) (PEG).
9. A method for laundering a textile, comprising:
a) exposing an item to a wash liquor comprising the detergent composition according to claim 1 ; and
b) completing at least one wash cycle.
10. The method of claim 9 , further comprising rinsing the textile.
11. The method of claim 9 , wherein the pH of the wash liquor is in the range 5.5 to 11.
12. The method of claim 9 , wherein the temperature of the wash liquor is in the range of 5 to 95° C.
13. The detergent composition of claim 1 , wherein the polypeptide having DNase activity comprises or consists of the polypeptide of SEQ ID NO: 6.
14. The detergent composition of claim 6 , wherein the polyol is selected from the group consisting of glycerol, (mono, di, or tri) propylene glycol, ethylene glycol, polyethylene glycol, sugar alcohols, sorbitol, mannitol, erythritol, dulcitol, inositol, xylitol and adonitol.
15. The detergent composition of claim 1 , formulated as a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid.
