KW - Inhibitor of protein synthesis

Figure 2. A) Sites of action of inhibitors of bacterial protein synthesis. B) Macrolide antibiotics share a common macrocyclic lactone ring structure & deoxy sugar residues. The structures for erythromycin & clarithromycin differ only at one position (circled in green). Structures reproduced from .

Erythromycin inhibits protein biosynthesis in ribosomes (mitoribosomes) located within the mitochondrion of the yeast cell, which results in a disruption of cytochrome biosynthesis with an adverse effect on respiration.

Definitely a good product review, but also very well structured from scientific point of view. Good references also. Will use it as a source for my next post about the different protein synthesis inhibitors.

T1 - Design, synthesis, and characterization of an ATP-peptide conjugate inhibitor of protein kinase A

Antibiotic Inhibition of Protein Synthesis

An ATP-peptide conjugate was synthesized as a bisubstrate analogue inhibitor of the serine/threonine kinase protein kinase A. The compound was found to be a linear, competitive inhibitor with respect to ATP substrate, exhibiting a Ki of 3.8μM. The compound was noncompetitive with respect to peptide substrate. The inhibitor was shown to be selective for protein kinase A versus the closely related protein kinase C as well as tyrosine kinase Csk. This analysis provides new evidence for the dissociative transition state of protein serine/threonine kinases and illustrates a simple method to convert a low affinity peptide substrate to a selective and moderately potent inhibitor for these enzymes.

[33] Shiga toxin as inhibitor of protein synthesis

Biological Role(s): DNA synthesis inhibitor Any substance that inhibits the synthesis of DNA. protein synthesis inhibitor A compound, usually an anti-bacterial agent or a toxin, which inhibits the synthesis of a protein. bacterial metabolite Any prokaryotic metabolite produced during a metabolic reaction in bacteria. antibiotic A substance that is biostatic or biocidal at low concentrations towards bacteria, yeasts, moulds, or other form of life, especially pathogenic or noxious organisms. Although the term was originally restricted to substances produced by microorganisms, its use was later expanded to include derivatives of such substances and it is now commonly used to include entirely synthetic compounds. (via heterocyclic antibiotic )

Many of the most effective antibiotics used in medicine today are small molecules produced by fungi. The properties of an antibiotic are sometimes determined by its activity on the different regions on the bacterial ribosome. These molecules are effective by inhibiting bacterial protein synthesis. The antibiotic Anisomycin is an effective inhibitor of fungal and protozoal growth. Anisomycin uses an effective blocking protein that works by shutting down the peptidyl transferase reaction within ribosomes. The ribosomes of eucaryotic mitochondria (and chloroplasts) will often resemble those of bacteria in their sensitivity to inhibitors. Therefore, some antibiotics such as Anisomycin can have a deletrious effect on human mitochondria.

Symptoms of Protein Synthesis Inhibitors in Sweet …

Anisomycin, also known as flagecidin is an antibiotic produced by Streptomyces griseolus which inhibits protein synthesis. Partial inhibition of DNA synthesis occurs at anisomycin concentrations that effect 95% inhibition of protein synthesis. Anisomycin can activate , and other pathways. Anisomycin is inactive against bacteria.
