Abstract
The present invention relates to a DNA construct exhibiting .beta.-1,3-glucanase activity, which DNA sequence comprises: a) the DNA sequence shown in SEQ ID No. 1 or SEQ ID No. 12, or b) an analogue of the DNA sequence defined in a), which i) is homologous with the DNA sequence defined in a), or ii) hybridizes with the same oligonucleotide probe as the DNA sequence defined in a), or iii) encodes a polypeptide which is homologous with the polypeptide encoded by a DNA sequence comprising the DNA sequence defined in a), or iv) encodes a polypeptide which is immunologically reactive with an antibody raised against the purified .beta.-1,3-glucanase derived from Oerksovia xanthineolytica LLG109 encoded by the DNA sequence defined in a). The DNA construct may further encode a mannose binding domain. The invention also relates to a DNA construct encoding a mannose binding domain. Further the invention relates to an expression vector comprising said DNA constructs, a cell harbouring said DNA constructs or expression vectors, a method of producing the novel enzyme, a novel enzyme preparation containing said novel enzyme, the use of the enzyme for degrading or modification of .beta.-glucan co…
