Evolutionary conundrum of RNase P: from a catalytic RNA form to a protein only enzyme form [PDF]

open access: yes, 2019
RNaza P je esencijalna endonukleaza koja katalizira procesiranje 5'-vodećeg slijeda pre-tRNA. Postoje dva tipa RNaze P: RNA-ovisni enzim tj ribonukleoprotein te isključivo proteinska RNaza P (PRORP).

The consequences of replicating in the wrong orientation: Bacterial chromosome duplication without an active replication origin [PDF]

open access: yes, 2015
Chromosome replication is regulated in all organisms at the assembly stage of the replication machinery at specific origins. In Escherichia coli the DnaA initiator protein regulates the assembly of replication forks at oriC.

Substrate recognition and cleavage-site selection by a single-subunit protein-only RNase P

open access: yesNucleic Acids Research, 2016
RNase P is the enzyme that removes 5′ extensions from tRNA precursors. With its diversity of enzyme forms—either protein- or RNA-based, ranging from single polypeptides to multi-subunit ribonucleoproteins—the RNase P enzyme family represents a unique ...

PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

open access: yesMolecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]

open access: yes, 2008
Maturation of tRNA precursors into functional tRNA molecules requires trimming of the primary transcript at both the 5' and 3' ends. Cleavage of nucleotides from the 3' stem of tRNA precursors, releasing nucleotide diphosphates, is accomplished in ...

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

open access: yesMolecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

Cryo-electron microscopy structure of an archaeal ribonuclease P holoenzyme

open access: yesNature Communications, 2019
Ribonulease P is a conserved ribozyme present in all kingdoms of life that is involved in the 5′ maturation step of tRNAs. Here the authors determine the structure of an archaeal RNase P holoenzyme that reveals how archaeal RNase P recognizes its tRNA ...

Bcheck: a wrapper tool for detecting RNase P RNA genes

open access: yesBMC Genomics, 2010
Background Effective bioinformatics solutions are needed to tackle challenges posed by industrial-scale genome annotation. We present Bcheck, a wrapper tool which predicts RNase P RNA genes by combining the speed of pattern matching and sensitivity of ...

RNase P Ribozyme Effectively Inhibits Human CC-Chemokine Receptor 5 Expression and Human Immunodeficiency Virus 1 Infection

open access: yesZoonotic Diseases, 2023
Developing novel antiviral agents and approaches is essential for the treatment against human and zoonotic viruses. We had previously produced RNase P-based ribozyme variants capable of efficiently cleaving mRNA in vitro.

Use of RNA secondary structure for evolutionary relationships : investigating RNase P and RNase MRP : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, New Zealand [PDF]

open access: yes, 1998
Bioinformatics is applied here to examine whether RNA secondary structure data can reflect distant evolutionary relationships. This is important when there is little confidence in sequence data such as when looking at the evolution of RNase MRP (MRP ...
