fusB is an allele of nadD, encoding nicotinate mononucleotide adenylyltransferase in Escherichia coli.

Abstract excerpt

Isolation of the temperature-sensitive Escherichia coli mutant 72c has been described previously. The mutant allele was named fusB and causes a pleiotropic phenotype, the most striking features of which, besides temperature sensitivity, are the inability to grow on synthetic medium and supersensitivity to trimethoprim, an antibiotic that inhibits the C1 metabolism. This work shows that the fusB mutation is a...
