Abstract: An enzyme exhibiting endo-?-1,4-glucanase activity which belongs to family 9 of glycosyl hydrolases is obtainable from or endogeneous to a strain belonging to the genus Bacillus such as Bacillus licheniformis, ATCC 14580; an isolated polynucleotide (DNA) molecule encoding an enzyme or enzyme core (the catalytically active domain of the enzyme) exhibiting endo-?-1,4-glucanase activity selected from (a) polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO:1 from nucleotide 76 to nucleotide 1455 or from nucleotide 76 to nucleotide 1941, (b) polynucleotide molecules that encode a polypeptide being at least 75% identical to the amino acid sequence of SEQ ID NO:2 from amino acid residue 26 to amino acid 485 or from amino acid residue 26 to amino acid residue 646, and (c) degenerate nucleotide sequences of (a) or (b), the expressed endoglucanase enzyme being useful in various industrial applications.

Abstract: A method for providing a hybrid polypeptide having an activity of interest, by i) performing PCR amplification using an uncharacterized DNA sample and oligonucleotide primers with homology to one or more known genes encoding a polypeptide exhibiting said activity of interest, to obtain one or more PCR products, ii) linking the obtained PCR products to a 5′ structural gene sequence and a 3′ structural gene sequence, wherein the 5′ and 3′ structural gene sequences are derived from one or more genes encoding a polypeptide exhibiting said activity of interest, to form hybrid DNA sequences, iii) expressing the resulting hybrid DNA sequences, and iv) screening the hybrid polypeptides to identify a sequence encoding a polypeptide exhibiting said activity of interest or a related activity.
