Isolation of Escherichia coli mutants defective in uptake of molybdate.

Journal of bacteriology - 1 Oct 1991

Hemschemeier S, Grund M, Keuntje B, Eichenlaub R

Abstract excerpt

For the study of molybdenum uptake by Escherichia coli, we generated Tn5lac transposition mutants, which were screened for the pleiotropic loss of molybdoenzyme activities. Three mutants A1, A4, and M22 were finally selected for further analysis. Even in the presence of 100 microM molybdate in the growth medium, no active nitrate reductase, formate dehydrogenase, and trimethylamine-N-oxide reductase were detected...
