Abstract
A method of measuring binding to subcellular particles was applied to binding of sulfate to cells and cell-free extracts of Salmonella typhimurium. Binding by extracts of derepressed cells but not by extracts of repressed cells was observed. Chemical changes of sulfate into non-binding compounds is probably not involved. This binding may be a step in active transport of sulfate. Data on preliminary separation of a radioactively labeled and presumably inactive binding site for [beta]-galactoside transport were presented.Keywords
