| 发明名称 | Porphyranases, and use thereof for hydrolyzing polysaccharides | ||
| 摘要 | The present invention relates to the isolation and to the characterization of two proteins having a novel enzymatic activity, i.e. a porphyranase activity. These proteins are useful for hydrolyzing polysaccharides containing sulfated agaro-colloids and for producing oligo-porphyrans, notably oligo-porphyrans with a defined structure and size. | ||
