A monosaccharide exotype algin lyase Aly-6 having M-tendency, and a coding gene thereof and use thereof. The amino acid sequence of the monosaccharide exotype algin lyase Aly-6 having M-tendency is shown as SEQ ID NO. 2. The nucleotide sequence encoding Aly-6 is shown as SEQ ID NO. 1. Aly-6 is obtained from the genome of bacterium MY04 of genus Flammeovirga, and can not only continuously degrade guluronic acid fragments of algin by means of external cleavage of monosaccharides, but also continuously degrade mannuronic acid fragments by means of external cleavage of monosaccharides, however, is more apt in degrading the mannuronic acid fragments. |
