ABSTRACT:
Three genes involved in the catabolism of chitin in Vibrio furnissii: endI encodes periplasmic chitodextrinase, exoI encodes periplasmic .beta.-N-acetylglucosaminidase, and exoII encodes aryl .beta.-N-acetylglucosaminidase are provided. The complete nucleotide sequence for each of the three genes and the complete amino acid for the corresponding enzymes are demonstrated along with host cells capable of expressing the recombinant enzymes. The present invention also describes four specific strains of V. furnissii having deletions in genes involved in the catabolic pathway of chitin and a process for the production of chitin oligosaccharides.
