Summary
Non-ribosomal peptide synthetases (NRPSs) are modular enzymes that create complex peptides using unusual building blocks. This chapter introduces NRPS enzymes and their assembly-line biosynthesis, highlighting structural biology advances.
Area of Science:
- Biochemistry
- Molecular Biology
- Structural Biology
Background:
- Non-ribosomal peptide synthetases (NRPSs) are crucial modular enzymes for natural product biosynthesis.
- Unlike ribosomal synthesis, NRPSs incorporate diverse amino acids and building blocks.
- NRPSs function via an assembly-line mechanism, tethering intermediates to carrier proteins.
Purpose of the Study:
- To introduce the fundamental biochemistry of NRPS enzymes.
- To illustrate NRPS common features using the nocardicin NRPS system.
- To review recent advances in NRPS structural biology.
Main Methods:
- Literature review of NRPS biochemistry and structural studies.
- Focus on the nocardicin NRPS system as a representative example.
- Analysis of recently determined large multidomain NRPS structures.
Main Results:
- NRPSs exhibit a modular enzymatic architecture.
- They employ a carrier protein-based assembly line for peptide synthesis.
- Structural studies reveal the organization of large multidomain NRPS complexes.
Conclusions:
- NRPSs are versatile biosynthetic enzymes with unique assembly-line mechanisms.
- The nocardicin system exemplifies key NRPS biochemical principles.
- Advances in structural biology provide insights into NRPS function and regulation.

13.3K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

7.8K
Ribosomes translate genetic information encoded by messenger RNA (mRNA) into proteins. Both prokaryotic and eukaryotic cells have ribosomes. Cells that synthesize large quantities of protein—such as secretory cells in the human pancreas—can contain millions of ribosomes.

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.

01:44Termination of Translation
25.6K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Structure of PeptidoglycanPeptidoglycan is a vital structural component of the bacterial cell wall, providing mechanical strength and shape to the cell. It consists of repeating units of two sugars—N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM)—linked by β-1,4 glycosidic bonds. These sugar chains are cross-linked by short peptide chains, forming a mesh-like polymer that surrounds the bacterial plasma membrane.Cytoplasmic Phase – Precursor SynthesisPeptidoglycan...
