The Photochemical Inactivation of Peptidyl Transferase Activity [PDF]
European Journal of Biochemistry, 1975 The photochemical oxidation of the 50‐S ribosomal subunit results in a rapid irreversible loss of peptidyl transferase activity. The first‐order rate of inactivation occurring during the first forty minutes suggests that a single reactive group is being inactivated.

Microbiology Spectrum, 2022 Phosphopantetheinyl transferases (PPTases) play important roles in activating apo-acyl carrier proteins (apo-ACPs) and apo-peptidyl carrier proteins (apo-PCPs) in both primary and secondary metabolism. PPTases catalyze the posttranslational modifications

A single Sfp-type phosphopantetheinyl transferase plays a major role in the biosynthesis of PKS and NRPS derived metabolites in Streptomyces ambofaciens ATCC23877. [PDF]
PLoS ONE, 2014 The phosphopantetheinyl transferases (PPTases) are responsible for the activation of the carrier protein domains of the polyketide synthases (PKS), non ribosomal peptide synthases (NRPS) and fatty acid synthases (FAS).

The Ribosomal Peptidyl Transferase [PDF]
Molecular Cell, 2007 Peptide bond formation on the ribosome takes place in an active site composed of RNA. Recent progress of structural, biochemical, and computational approaches has provided a fairly detailed picture of the catalytic mechanism of the reaction. The ribosome accelerates peptide bond formation by lowering the activation entropy of the reaction due to ...

Peptidyl transferase: ancient and exiguous [PDF]
Chemistry & Biology, 2000 The finding that the universal ribosomal peptidyl transferase is an RNA enzyme casts new light on its ancient origins, on the use of transition state analogues for ribozymes, and on the role of selection-amplification in studies of molecular evolution.

Hydrolysis of fMet-tRNA by Peptidyl Transferase [PDF]
Proceedings of the National Academy of Sciences, 1971 Escherichia coli and rabbit reticulocyte (f[ 3 H]Met-tRNA·AUG·ribosome) intermediates undergo hydrolysis, with release of f[ 3 H]methionine, upon addition of tRNA or CpCpA in the presence of acetone.

Nuclear translation or nuclear peptidyl transferase? [PDF]
Nucleus, 2012 It is widely accepted that protein synthesis occurs in the cytoplasms of eukaryotic cells, but some investigators believe that it also occurs in the nucleus. In spite of experiments performed in several labs over many years, the issue of nuclear translation remains unresolved.
