  Synthesis of 13C-labeled γ-hydroxybutyrates for EPR studies with 4-hydroxybutyryl-CoA dehydratase

  摘要：

  4-Hydroxybutyryl-CoA dehydratase from Clostridium aminobutyricum catalyses the reversible dehydration of its substrate 4-hydroxybutyryl-CoA (4-HB-CoA) to crotonyl CoA. The enzyme contains one [4Fe-4S](2+) cluster and one flavin adenine dinucleotide (FAD) molecule per homotetramer. Incubation of the enzyme with its substrate under equilibrium conditions followed by freezing at 77 K induced the EPR-spectrum of a neutral flavin semiquinone (g = 2.005, linewidth 2.1 mT), while at 10 K additional signals were detected. In an attempt to characterize these signals, 4-HB-CoA molecules specifically labeled with C-13 have been synthesized. This was achieved via C-13-labeled gamma-butyrolactones, which were obtained from C-13-labeled bromoacetic acids by efficient synthetic routes. Incubation of the C-13-labeled 4-hydroxybutyrate-CoA molecules with 4-hydroxybutyryi-CoA dehydratase did not lead to marked broadening of the signals.(C) 2004 Elsevier Inc. All rights reserved.
