Biocatalyst | Genome Mining | Functional Exploration from biodiversity | High throughput enzyme screening



About the Platform 

Located at Genoscope (CEA sequencing center for environmental genomics), this platform is dedicated to broaden the field of industrial applications by mining genome by a sequence driven approach to discover novel enzymatic activities. To explore the microbial biodiversity of genes coding for enzymes, we have developed a high throughput process to select, clone the corresponding gene, express and screen the enzymes for the desired activity.

The use of this platform led to the discovery of new enzyme catalysing new nitrilases (Vergne-Vaxelaire et al., 2013), baeyer-villigerases (Reignier et al., 2014), dioxygenases (Baud et al., 2014), aldolases (Helaine et al., 2015; de Berardinis et al., 2016; Victor et al., 2018), aminotransferases (Heuson et al., 2016; Guerard-Helaine et al., 2017, Heuson et al., 2018), wild type amine deshydrogenases (Mayol et al., 2016), sugar kinases (Vergne- Vaxelaire et al., 2018).


  • From a set of experimentally known enzymes provided by the user, representative sequences from biodiversity will be selected using our bioinformatic tool
  • The corresponding genes will be cloned in a expression vector with/without a Histag depending the user need. - The gene collection will be over-expressed in E. coli and the cell-free extract will be prepared in 96-wells
  • The screening on 5 substrates maximum will be performed using UV spectrophotometry or Mass-spectrometry (LC/MS) detection. Nevertheless, expensive substrates (>100 euros/mg) will be provided by the user.
  • At the end of the process a list of enzymes catalysing the desired reaction will be delivered to the user.
  • Further work can then be considered on a collaboration basis.
