RESUMO

We have isolated numerous mutants containing mutations in the salvage pathways of purine synthesis. The mutations cause deficiencies in adenine phosphoribosyltransferase (adeF), in hypoxanthine-guanine phosphoribosyltransferase (guaF), in adenine deaminase (adeC), in inosine-guanosine phosphorylase, (guaP), and in GMP reductase (guaC). The physiological properties of mutants containing one or more of these mutations and corresponding enzyme measurements have been used to derive a metabolic chart of the purine salvage pathway of Bacillus subtilis.
