The beta-1,4-mannanase 5C gene (man5C) of Vibrio sp. strain MA-138 was cloned and expressed in Escherichia coli. The man5C gene consisted of 2,010 bp nucleotides encoding a protein of 669 amino acids with a predicted molecular weight of 76,309. beta-1,4-Mannanase (Man5C) is a modular enzyme composed of a catalytic module belonging to glycoside hydrolase(More)
PhiC31 integrase has the potential to achieve long-term transgene expression because of site-specific and unidirectional recombination. In this study, plasmid DNA (pDNA) encoding Gaussia luciferase (Gluc) cDNA was constructed and the optimal condition for long-term gene expression using phiC31 integrase in mouse liver after hydrodynamic injection was(More)
The xylA gene from a marine bacterium, Vibrio sp. strain XY-214, encoding d-xylose isomerase (XylA) was cloned and expressed in Escherichia coli. The xylA gene consisted of 1,320-bp nucleotides encoding a protein of 439 amino acids with a predicted molecular weight of 49,264. XylA was classified into group II xylose isomerases. The native XylA was estimated(More)
The beta-1,3-xylosidase gene (xloA) of Vibrio sp. strain XY-214 was cloned and expressed in Escherichia coli. The xloA gene consisted of a 1,608-bp nucleotide sequence encoding a protein of 535 amino acids with a predicted molecular weight of 60,835. The recombinant beta-1,3-xylosidase hydrolyzed beta-1,3-xylooligosaccharides to D-xylose as a final product.
The cell wall of the red alga Bangia atropurpurea is composed of three unique polysaccharides (beta-1,4-mannan, beta-1,3-xylan, and porphyran), similar to that in Porphyra. In this study, we visualized beta-mannan in the regenerating cell walls of B. atropurpurea protoplasts by using a fusion protein of a carbohydrate-binding module (CBM) and green(More)
