Abstract:
A new chitinase gene, chi92, encoding the largest known chitinase from Streptomyces olivaceoviridisATCC 11238 was sequenced by means of different PCR-methods. The cloned gene was expressed in E. coliand the recombinant protein could be detected by Western-blot analysis. The multiplicity of chitinolytic enzymes of this strain is discussed.
Keywords:chitinase gene  inverse PCR  multiplicity  RLM-RAGS  Streptomyces olivaceoviridis
