Summary
New antibiotic targets are essential for fighting resistant bacteria. Phage-related ribosomal proteases (Prps) are a novel target, crucial for bacterial ribosome function, offering a new therapeutic strategy.
Area of Science:
- Microbiology
- Structural Biology
- Drug Discovery
Background:
- Antimicrobial resistance necessitates novel therapeutic targets and mechanisms.
- Existing antimicrobials often target known pathways, limiting efficacy against resistant strains.
- Phage-related ribosomal proteases (Prps) represent a newly identified class of essential bacterial enzymes.
Purpose of the Study:
- To investigate phage-related ribosomal proteases (Prps) as a potential antibiotic target.
- To analyze the discovery, function, and structural features of Prps.
- To provide a foundation for developing novel therapeutics against Prp in key pathogens.
Main Methods:
- Bioinformatic analysis of Prp sequences and structures.
- Structural characterization of identified Prps.
- Comparative analysis of Prp across different bacterial species.
Main Results:
- Prps are essential for bacterial ribosome biogenesis via cleavage of ribosomal protein L27.
- Specific bacterial pathogens like *Staphylococcus aureus*, *Clostridioides difficile*, and *Streptococcus pneumoniae* possess unique N-terminal extensions on L27 targeted by Prps.
- Structural insights into Prp provide a basis for understanding their mechanism of action.
Conclusions:
- Inhibition of Prps offers a promising alternative strategy to traditional ribosome-targeting antibiotics.
- Targeting Prps could overcome existing antimicrobial resistance mechanisms.
- Further research into Prp structure and function can guide the development of selective antimicrobial agents.

Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...

3.6K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.

17.3K
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

01:20Viral Replication: Lytic Cycle
173
Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...

01:30Lytic Cycle of Bacteriophages
71.7K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...
