  • Title: Cloning and sequencing of cellulase cDNA from Aspergillus kawachii and its expression in Saccharomyces cerevisiae.
    Author: Sakamoto S, Tamura G, Ito K, Ishikawa T, Iwano K, Nishiya N.
    Journal: Curr Genet; 1995 Apr; 27(5):435-9. PubMed ID: 7586029.
    Abstract:
    The cDNA encoding the endo-beta-1,4-glucanase (carboxymethylcellulase; CMCase-I) from Aspergillus kawachii IFO 4308 was cloned. Nucleotide-sequence analysis of the cloned cDNA insert showed a 717-bp open reading frame that encoded a protein of 239 amino-acid residues. The predicted amino-acid sequence of the mature protein had considerable homology with the protein sequence of the FI-CMCase of Aspergillus aculeatus. The cDNA was introduced into Saccharomyces cerevisiae. The expressed enzyme had carboxylmethylcellulase activity, identified by clear zones on a CMC-agar plate after Congo Red staining.
