VPR enzyme of B. bruxellensis has been identified through the expression of a functional protein in S. cerevisiae. The Rossmann fold-like region of VPR, involved in the reductase activity, is a conserved domain in D. bruxellensis. No direct correlation exists between the genetic polymorphism of VPR gene and the production of volatile phenols. VPR is a SOD; this evidence is particularly interesting in terms of adaptive evolution of the species to wine environment.
