YjjG, a dUMP phosphatase, is critical for thymine utilization by Escherichia coli K-12.

چکیده

Exogenous thymine must be converted to thymidine to enable a thyA (thymidylate synthase) mutant to grow. The deoxyribose in the thymidine comes from dUMP, which must first be dephosphorylated. The nucleotidase YjjG is critical for this step. A yjjG thyA mutant cannot use thymine for growth on a glucose minimal medium.

Loss of deoxyribonucleic acid-thymine during thymine starvation of Escherichia coli.

A substantial loss of deoxyribonucleic acid-thymine occurs during thymine starvation of several thymine auxotrophs derived from Escherichia coli strains B, 15, and K-12.

Thymineless death in Escherichia coli 15T- and recombinants of 15T- and Escherichia coli K-12.

Thymineless death was examined in Escherichia coli 15T(-) and recombinants of 15T(-) and E. coli K-12. Those strains that were very sensitive to thymine deprivation were also very sensitive to a variety of inducing agents (mitomycin C, ultraviolet light, hydroxyurea, and nalidixic acid). Those strains that were relatively resistant to thymineless death were also relatively resistant to the indu...

Utilization of 5-bromouracil by thymineless bacteria.

Several thymineless Escherichia coli strains have been examined for their ability to replicate their deoxyribonucleic acid when bromouracil is substituted for thymine. The procedure we describe was used to identify a thymineless strain with characteristics relatively favorable to its use in bromouracil labeling experiments. In addition, mutants with an "absolute" thymine requirement could be ea...

The Properties of a Bacteriophage T5 Mutant Unable to Induce Deoxyuridine 5’-Triphosphate Nucleotidohydrolase

Bacteriophage T5 induces a deoxyuridine B’-triphosphate nucleotidohydrolase (dUTPase) activity during infection of Escherichiu coli. A T5 mutant (T5 dut) unable to induce this dUTPase activity has been isolated. Although this mutant is viable, the E. coli dUTPase activity is not sufficiently active to exclude uracil from the progeny DNA and about 3% of the thymine is replaced by uracil. When th...
