Congratulations to Xin Guan and Basil Nikolau on their new Plant Journal article, "A phosphopantetheinyl transferase that is essential for mitochondrial fatty acid biosynthesis," epublished on September 24.
Biotin is a water-soluble vitamin that is biosynthesized by plants, and some bacteria and fungi. One of its biochemical functions is as a covalently-bound cofactor on a family of enzymes that catalyze reactions in a variety of crucial metabolic processes. Examples of such enzymes are acetyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, propionyl-CoA carboxylase and geranoyl-CoA carboxylase, which are required for lipogenesis, amino acid metabolism and isoprenoid metabolism.
