• PubMed Abstract: 
  

  The biosynthesis of the essential amino acid lysine in higher fungi and cyanobacteria occurs via the alpha-aminoadipate pathway, which is completely different from the lysine biosynthetic pathway found in plants and bacteria. The penultimate reaction in the alpha-aminoadipate pathway is catalysed by NADPH-dependent saccharopine reductase. We set out to determine the structure of this enzyme as a first step in exploring the structural biology of fungal lysine biosynthesis.
