Molecular study and overexpression of the Clostridium cellulolyticum celF cellulase gene in Escherichia coli

Article Abstract:

The cloning, sequencing and expression of the celF gene of Clostridium cellulolyticum corresponding to the open reading frame-1 in the cel gene cluster are discussed. Expression of celF in Escherichia coli under standard conditions caused the recombinant protein to aggregate and form inclusion bodies. A mature form of CelF was generated after optimizing the induction conditions. CelF hydrolyzed cellulose but was poorly active on substituted cellulose.

YeiL, the third member of the CRP-FNR family in Escherichia coli

Article Abstract:

Research has been conducted on YeiL protein from Escherichia coli. The characterization of this protein has been carried out, and its functions have been defined via the study of the physiological consequences of yeiL gene inactivation and yeiL gene expression regulation.
