Abstract:
:The beta-agarase C gene (agaC) of a marine bacterium, Vibrio sp. strain PO-303, consisted of 1,437 bp encoding 478 amino acid residues. beta-Agarase C was identified as the first beta-agarase that cannot hydrolyze neoagarooctaose and smaller neoagarooligosaccharides and was assigned to a novel glycoside hydrolase family.
