Research output: Patent


An enzyme exhibiting rhamnogalacturonase activity, which enzyme: a) is encoded by the DNA sequence shown in SEQ ID No. 1 or a sequence homologous thereto encoding a polypeptide with RGase activity, b) has the amino acid sequence shown in SEQ ID No. 2 or an analogue thereof, c) is reactive with an antibody raised against the enzyme encoded by the DNA sequence shown in SEQ ID No. 1, d) has a pH optimum above pH 5, and/or e) has a relative activity of at least 30% at a pH in the range of 5.5-6.5. The enzyme may be used for reducing the viscosity of a plant cell wall material and for extracting high molecular weight molecules from a plant cell wall material.
