A systematic procedure for the kinetic study of irreversible inhibition when the enzyme is consumed in the reaction which it catalyses, has been developed and analysed. Whereas in most reactions the enzymes are regenerated after each catalytic event

Before CI isomerizes to C*I, we detect a competitive phase of inhibition (Ki = k5/k4 = 0.05 microM) which eventually, by increasing the concentration of I, becomes linear mixed noncompetitive and involves C*I in place of CI. The equilibration of C an

The effect of NH4+ and K+ ions on the activity of ribosomal peptidyltransferase was investigated in a model system derived from Escherichia coli, in which AcPhe-puromycin is produced by a pseudo-first-order reaction between the preformed AcPhe-tRNA-p

In an effort to elucidate the role of potassium ions in the formation of peptide bond, we have used the reaction between puromycin and a ribosomal complex (from rabbit reticulocytes) bearing the donor substrate, AcPhe-tRNA, prebound at the so-called

We have developed an in vitro system for the determination of peptidyltransferase activity in rabbit reticulocyte ribosomes. Using this system, a detailed kinetic analysis of a model reaction for peptidyltransferase is described, with AcPhe-tRNA as t

The inhibition of peptide bond formation by spiramycin was studied in an in vitro system derived from Escherichia coli. Peptide bonds are formed between puromycin (S) and Ac-Phe-tRNA, which is a component of complex C, i.e., of the [Ac-Phe-tRNA-70S r

In a system derived from Escherichia coli, we carried out a detailed kinetic analysis of the inhibition of the puromycin reaction by lincomycin. N-Acetylphenylalanyl-tRNA (Ac-Phe-tRNA; the donor) reacts with excess puromycin (S) according to reaction

A cell-free system derived from Escherichia coli has been used in order to study the kinetics of inhibition of peptide bond formation with the aid of the puromycin reaction in solution. A similar study has been carried out earlier on a solid support

The puromycin reaction, catalyzed by the ribosomal peptidyltransferase, has been carried out so as to make the definition of two distinct parameters of this reaction possible. These are (a) the final degree of the reaction which gives the proportion
