malfunction | a truB null mutant grows normally on all growth media tested, but exhibits a competitive disadvantage in extended co-culture with its wild-type progenitor. The mutant phenotype can be complemented by both the cloned truB gene and by a D48C, catalytically inactive allele of truB. The truB mutant also exhibits a defect in survival of rapid transfer from 37 to 50°C | Escherichia coli |
physiological function | pseudouridine-55 synthase is responsible for modifying all tRNA molecules in the cell at the uridine55 position. TruB-effected pseudouridine55 modification of tRNA is not essential, but contributes to thermal stress tolerance in Escherichia. coli, possibly by optimizing the stability of the tRNA population at high temperatures | Escherichia coli |
