Provided are a method of decolorizing a composition including pectate lyase, and a decolorizing composition for the composition including pectate lyase.

The present invention relates to a multi-functional peptide benefiting expression, purification, stabilization and catalytic efficiency of recombinant proteins, which relates to the field of enzyme engineering and protein purification. The present invention provides a self-assembling amphipathic peptide, which fused with proteins including alkaline polygalacturonate lyase (PGL), lipoxygenase (LOX) and green fluorescent protein (GFP), which leads to successful purification by the nickel affinity chromatography with recovery rates were 47.01%, 39.01% and 56.1%, respectively. Furthermore, the expression quantity and thermostability of the three proteins were enhanced in different degree. Of which the half-life of the PGL-S1v1 and LOX-S1v1 were 2.3 and 3.8-fold as compared with the corresponding wild-type and the specific activity were 1.1 and 1.9-fold increase, respectively. The crude enzyme activity of PGL-S1v1 was 9-fold increase than the PGL.

The invention is in the field of protein chemistry, in particular in the field of enzymology. It provides pectinases, i.e. polypeptides with pectin-degrading properties. In particular the invention provides polypeptides with pectate lyase activity (EC 4.2.2.2). Enzymes according to the invention have improved properties, such as improved thermostability and decreased calcium dependence.

Methods to reduce sticky and fluff induced rewinder breaks by reducing the adhesive character of adhesive materials, fluff and sticky contaminants in fibers are described. One method involves contacting the fibers with a composition containing at least one of each of a cellulase, a hemicellulase, a -glucosidase, a lipase, an esterase, a pectinase, a pectate lyase and a laccase for a sufficient time and in a sufficient amount to control the removal or controlling adhesive materials, fluff and sticky contaminants present in the fibers. Preferably, the fibers are recycled fibers originating from a variety of sources such as old corrugated containers, old newsprint, mixed office waste, and the like. Resulting paper products formed from the processed fibers are also described as well as methods to make them.

The invention relates to processes for the conversion of biomass into carbohydrates, notably reducing sugars. It provides means and methods for increasing the yield of enzymatic digestion of a biomass, in particular in methods wherein cellulose is converted into sugars using a cellulose-converting enzyme. More in particular, the invention provides a method for producing a reducing sugar from a lignoceliulosic material, wherein the lignocellulosic material is contacted with a pectate lyase at a pH between 9 and 12, wherein the pectate lyase comprises an amino acid sequence according to SEQ ID NO: 1 or an amino acid sequence at least 70% identical with SEQ ID NO: 1.
