Unger, Leon (University of Illinois, Urbana), and R. D. DeMoss. Metabolism of a proline analogue, l-thiazolidine-4-carboxylic acid, by Escherichia coli. J. Bacteriol. 91:1564-1569. 1966.-Resting cells of Escherichia coli K-12, pregrown in a proline- and thioproline-free medium, oxidize the proline analogue, l-thiazolidine-4-carboxylic acid (l-thioproline), without a lag with the consumption of 1 atom of oxygen per mole of thioproline. The organism also oxidizes cysteine and formaldehyde, the chemical precursors of thioproline. The total oxygen consumed is the same whether the substrate is thioproline, cysteine, formaldehyde, or an equimolar mixture of cysteine and formaldehyde. The results suggest that neither cysteine nor formaldehyde are free intermediates in the oxidative pathway. Thioproline is available as a metabolic carbon source for the synthesis of the ribonucleic acid bases, guanine and uracil.
