Abstract |
Mycothiol (MSH) was reported to be the dominant low molecular weight thiol in members of the Actinobacteria. In this study, a simple, fast, and sensitive method for qualitative and quantitative determination of MSH molecules was developed based on maleylpyruvate isomerase (MPI) from Corynebacterium glutamicum. The principle of this method is that the activity of MPI from C. glutamicum was dependent on MSH molecules. It was found that this MPI activity displayed a linear response (R (2) = 0.9928) at MSH amounts ranging from 0.12 to 3.98 pmol in the defined assay system. This observation was applied to calculate the MSH levels, and the newly developed method was compared with thiol-specific fluorescent-labeling high-performance liquid chromatography method. Forty-eight genera of Actinobacteria were screened for MSH and 43 genera were reported for MSH occurrence, and the MSH levels in Actinobacteria were determined to be 0.01 to 9.69 μmol/g of residual dry cell weight.
