Disruption of a glutathione reductase encoding gene in Acremonium chrysogenum leads to reduction of its growth, cephalosporin production and antioxidative ability which is recovered by exogenous methionine.

Abstract excerpt

Glutathione is a ubiquitous thiol in eukaryotic cells, and its high intracellular ratio of reduced form (GSH) to oxidized form (GSSG) is largely maintained by glutathione reductase (GR) using NADPH as electron donor. glrA, a glutathione reductase encoding gene, was found and cloned from Acremonium chrysogenum by searching its genomic sequence based on similarity. Its deduced protein exhibits high similarity to...
