title: Expression of the cellulase (FI-CMCase) gene of Aspergillus aculeatus in Escherichia coli.
abstract: FI-CMCase cDNA of Aspergillus aculeatus was expressed in Escherichia coli by using the tac promoter of E. coli. Transformants of E. coli harboring a plasmid pHEM06 containing mature form FI-CMCase cDNA produced FI-CMCase in the cytoplasm of the cells. The enzyme from E. coli cells was purified to yield 56% and it was immunological identical to that of FI-CMCase purified from A. aculeatus.
