The present invention relates to polynucleotides encoding particular N-acetylmuramidases, which are cell wall lytic enzymes, of Streptomyces rutgersensis origin. The invention also relates to vectors comprising the polynucleotides encoding the N-acetylmuramidases, and also relates to host cells transformed with the vectors.

Gene of cell wall lytic enzyme, and vector containing said gene and

Disclosed is a cellobiose phosphorylase gene coding for a protein consisting of the amino acid sequence of SEQ ID NO: 16 as set forth in the Sequence Listing, a plasmid vector comprising the cellobiose phosphorylase gene and a transformant transformed with the plasmid vector.
