Phenyllactic acid (PLA) is a novel antimicrobial compound. A novel NADH-dependent d-lactate dehydrogenase (d-LDH), named as LF-d-LDH0653, with high phenylpyruvate (PPA) reducing activity was isolated from Lactobacillus fermentum JN248. Its optimum pH and temperature were 8.0 and 50 °C, respectively.

In this work, we describe the construction of a synthetic metabolic pathway enabling direct biosynthesis of 1,3-propanediol (PDO) from glucose via the Krebs cycle intermediate malate. This non-natural pathway extends a previously published synthetic pathway for the synthesis of (L)-2,4-dihydroxybutyrate

High-density lipoprotein (HDL) particles are cholesterol and lipid transport containers. Mature HDL particles destined for the liver develop through the formation of intermediate discoidal HDL particles, which are the primary acceptors for cholesterol. Here we present the three-dimensional structure of
