[Solubilizing effect of anionic detergents on cobalamin-protein compounds in Propionibacterium shermanii cells]

The effect of some anionic detergents on Propionibacterium shermanii cells was studied. The correlation was investigated between detergent concentrations and the content of solubilized protein in cell-free extracts. Sodium dodecyl sulfate, sodium deoxycholate and sodium cholate were shown to be capable of extracting cobalamin-protein and flavin-protein compounds from P. shermanii cells.
