Described is a method for the conversion of 3-methylcrotonyl-CoA into 3-hydroxy-3- methylbutyric acid comprising the steps of: (a) enzymatically converting 3-methylcrotonyl-CoA into 3-hydroxy-3-methylbutyryl-CoA; and (b) further enzymatically converting the thus produced 3-hydroxy-3-methylbutyryl-CoA into 3-hydroxy-3-methylbutyric acid wherein the enzymatic conversion of 3-hydroxy-3-methylbutyryl-CoA into 3-hydroxy-3-methylbutyric acid according to step (b) is achieved by first converting 3-hydroxy-3-methylbutyryl-CoA into 3-hydroxy-3-methylbutyryl phosphate and then subsequently converting the thus produced 3-hydroxy-3-methylbutyryl phosphate into 3-hydroxy-3-methylbutyric acid.

Methylcitric acid (MCA) was synthesised in Reformatsky reaction (2RS, 3RS stereoisomers) and in the nucleophilic addition (2RS, 3SR stereoisomers). The stereoselectivity of these reactions was analysed. H-1 and C-13 NMR spectra of diastereoisomers of methylcitric acid were recorded and interpreted. The values of H-1 chemical shifts and H-1-H-1 coupling constants were analysed. Proton-decoupled high-resolution C-13 NMR spectra of MCA diastereoisomers were measured in a series of dilute water solutions of various acidities. These data may provide a basis for unequivocal determination of the presence of MCA in the urine samples of patients' suffering from propionic acidemia, methylmalonic aciduria, or holocarboxylase synthetase deficiency. NMR spectroscopy enables determination of MCA diastereoisomers in body fluids and can be a complementary and useful diagnostic tool. (C) 2006 Elsevier B.V. All rights reserved.
