Involvement of the oxidative pentose phosphate pathway in thiamine biosynthesis in Salmonella typhimurium.

Abstract excerpt

purF mutants of Salmonella typhimurium are known to require a source of both purine and thiamine; however, exogenous pantothenate may be substituted for the thiamine requirement. We show here that the effect of pantothenate is prevented by blocks in the oxidative pentose phosphate pathway, gnd (encoding gluconate 6-phosphate [6-P] dehydrogenase) or zwf (encoding glucose 6-P dehydrogenase). We further show that...
