Summary
This summary is machine-generated.Sirtuin proteins, NAD+-dependent enzymes, catalyze deacylation. Limited knowledge exists on their diverse deacylase activities and physiological roles due to a lack of specific research tools.
Area Of Science
- Biochemistry
- Medicinal Chemistry
- Molecular Biology
Background
- Sirtuins are NAD+-dependent deacylases found across all kingdoms of life.
- Seven sirtuin proteins (SIRT1-7) exist in mammals, including humans.
- Sirtuins remove various acyl groups from lysine residues on proteins.
Purpose Of The Study
- To provide an updated account of sirtuin deacylase activities.
- To explore the biochemical and medicinal chemistry perspectives of sirtuin functions.
- To highlight the limited understanding of sirtuin (patho)physiological roles.
Main Methods
- Review of existing literature on sirtuin deacylase activities.
- Biochemical analysis of sirtuin catalytic functions.
- Medicinal chemistry approaches to sirtuin research.
Main Results
- Sirtuins exhibit diverse deacylase activities on various Nε-acyl-lysine substrates.
- Substrates range from acetyl to succinyl and myristoyl modifications.
- Knowledge gaps exist regarding the specific physiological roles of individual deacylase activities.
Conclusions
- Further research is needed to elucidate the specific roles of sirtuin deacylase activities.
- Development of deacylase-selective sirtuin mutants and inhibitors/activators is crucial.
- Understanding sirtuin functions has implications for human health and disease.

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
Cellular respiration is a fundamental metabolic process that enables organisms to generate energy from organic molecules. One of its central pathways is the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle, which plays a crucial role in energy production and biosynthetic processes.Conversion of Pyruvate to Acetyl-CoAThe pyruvate generated from glycolysis undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, producing acetyl-CoA, one molecule of NADH, and one...
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...
