Life, 2020 The peptidyl transferase center (PTC) is the catalytic center of the ribosome and forms part of the 23S ribosomal RNA. The PTC has been recognized as the earliest ribosomal part and its origins embodied the First Universal Common Ancestor (FUCA). The PTC

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]
, 1965 The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Single‐chain ribosome inactivating proteins from plants depurinate Escherichia coli 23S ribosomal RNA [PDF]
FEBS Letters, 1991 The rRNA N‐glycosidase activities of the catalytically active A chains of the heterodimeric ribosome inactivating proteins (RIPs) ricin and abrin, the single‐chain RIPs dianthin 30, dianthin 32, and the leaf and seed forms of pokeweed antiviral protein (PAP) were assayed on E. coli ribosomes. All of the single‐chain RIPs were active on E.

Origin and evolution of the Peptidyl Transferase Center from proto-tRNAs
FEBS Open Bio, 2014 We tested the hypothesis of Tamura (2011) [3] that molecules of tRNA gave origin to ribosomes, particularly to the Peptidyl Transferase Center (PTC) of the 23S ribosomal RNA.

The 23S Ribosomal RNA Mutation Database (23SMDB) [PDF]
Nucleic Acids Research, 1996 The 23S Ribosomal RNA Mutation Database (23SMDB), provides a list of mutated positions in 23S ribosomal RNA from Escherichia coli and the identity of each alteration. Information provided for each mutation includes: (i) a brief description of the phenotypes(s) associated with each mutation, (ii) whether a mutant phenotype has been detected by in vivo ...

Solution structure of the A loop of 23S ribosomal RNA [PDF]
Proceedings of the National Academy of Sciences, 2001 The A loop is an essential RNA component of the ribosome peptidyltransferase center that directly interacts with aminoacyl (A)-site tRNA. The A loop is highly conserved and contains a ubiquitous 2′- O -methyl ribose modification at position U2552.

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]
, 2012 Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

Optimization of an in vitro transcription/translation system based on Sulfolobus solfataricus cell lysate. [PDF]
, 2018 A system is described which permits the efficient synthesis of proteins in vitro at high temperature. It is based on the use of an unfractionated cell lysate (S30) from Sulfolobus solfataricus previously well characterized in our laboratory for ...

The Central Symbiosis of Molecular Biology: Molecules in Mutualism. [PDF]
, 2017 As illustrated by the mitochondrion and the eukaryotic cell, little in biology makes sense except in light of mutualism. Mutualisms are persistent, intimate, and reciprocal exchanges; an organism proficient in obtaining certain benefits confers those on ...
