摘要:
An isolated endo-fucoidan-lyase is described. The enzyme acts on fucoidan, has a pH optimum from 6 to 10, and has an optimum pH from 30 to 40° C. The enzyme can be isolated from Flavobacterium sp. FERM BP-5402. The enzyme is used to obtain sugar compounds which are useful in the study on carbohydrates.

摘要:
A method is provided for the quantitative determination of L-fucose in a sample solution. According to the method an L-fucose dehydrogenase having its optimum pH around neutrality is allowed to act upon the sample solution in the presence or absence of an .alpha.-L-fucosidase, and the amount of reduced nicotinamide adenine dinucleotide thus formed is measured.
