Abstract
The invention relates to the novel Cytophaga drobachiensis strain deposited in the DSMZ Collection (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (German Collection of Microorganisms and Cell Cultures)) on May 8, 1998 under the number DSM 12170, the agaA gene coding for a &bgr;-agarase and having SEQ ID No. 1, the agaB gene coding for a &bgr;-agarase and having SEQ ID No. 3, said genes coding for a &bgr;-agarase of Cytophaga drobachiensis DSM 12170, and the specific nucleic acid sequence of the agaA gene coding for a specific peptide fragment AgaA′ which has conserved &bgr;-agarase activity, and having SEQ ID No. 5, as well as the protein AgaA of C. drobachiensis DSM 12170 having SEQ ID No. 2, the protein AgaB of C. drobachiensis DSM 12170 having SEQ ID No. 4 and said peptide fragment AgaA′ of C. drobachiensis DSM 12170 having SEQ ID No. 6.
