title: New chromatographic form of phenylalanine transfer ribonucleic acid from Escherichia coli growing exponentially in a low-phosphate medium.
abstract: Reversed-phase chromatography has been used to detect the presence of a new form of phenylalanyl-transfer ribonucleic acid (Phe-tRNA) from Escherichia coli growing exponentially in media containing low but nonlimiting levels of inorganic phosphate. The amount of this extra Phe-tRNA form is greatest in slowly growing cells (0.8 generations/h), and becomes negligible in media supporting a rapid growth rate (2.14 generations/h).
