HETERO-TRANSGLYCOSYLASE AND USES THEREOF

摘要

The present invention relates to a hetero-transglycosylase protein having cellulose:xyloglucan endotransglucosylase (CXE) activityin addition to mixed-linkage beta-glucan : xyloglucan endotransglucosylase (MXE) activity. The protein may comprisethe amino acid sequence ofany one of SEQ ID NOs: 2, 6 and 8or a functional fragment thereof; or an amino acid sequence having at least 60% sequence identity to any one of SEQ ID NO: 2, 6 and 8, or to SEQ ID NO: 2 from amino acid 22 to 280, to SEQ ID NO: 6 from amino acid 26 to 283, or to SEQ ID NO: 8 from amino acid 29 to 287. The invention furthermore relates to an isolated nucleic acid encoding the protein described herein, a chimeric gene comprising, inter alia, the nucleic acid described herein, a vector comprising said chimeric gene, a host cell comprising said vector or said chimeric gene and an according transgenic plant. Further disclosed herein in are a method of producing a transgenic plant and a method of improving propertiesof cellulosic material.
