Pleiotropic phenotype of an Escherichia coli mutant lacking leucyl-, phenylalanyl-transfer ribonucleic acid-protein transferase

Abstract
A mutant of E. coli that lacks leucyl-, phenylalanyl-tRNA-protein transferase [EC 2.3.2.6] had diminished activities of L-phenylalanyl-tRNA synthetase and tryptophanase, grew faster than its parent with aspartic acid as the sole N source, accumulated higher levels of enterochelin in the medium during Fe limitation and exhibited an abnormal morphology.
