title: Particular influence of leucine peptides on lysyl-transfer ribonucleic acid ligase formation in a mutant of Escherichia coli K-12.
abstract: l-Leucine dipeptides can enhance lysyl-transfer ribonucleic acid ligase activity 15- to 20-fold in a mutant of Escherichia coli K-12. Evidence indicates the peptides act per se.
