SIRT2 and lysine fatty acylation regulate the transforming activity of K-Ras4a

open access: yeseLife, 2017
Ras proteins play vital roles in numerous biological processes and Ras mutations are found in many human tumors. Understanding how Ras proteins are regulated is important for elucidating cell signaling pathways and identifying new targets for treating ...

Optimization of the Enzymatic Acylation Reaction Conditions of Vitis davidii Malvidin

open access: yesShipin gongye ke-ji, 2022
In order to increase the structural stability of anthocyanins, taking Vitis davidii malvidin as sample and the lipase CAL-B as catalyst, the effects of reaction time, temperature, and substrate molar ratio on enzymatic acylation were investigated.

Site-specific analysis of protein S-acylation by resin-assisted capture[S]

open access: yesJournal of Lipid Research, 2011
Protein S-acylation is a major posttranslational modification whereby a cysteine thiol is converted to a thioester. A prototype is S-palmitoylation (fatty acylation), in which a protein undergoes acylation with a hydrophobic 16 carbon lipid chain ...

The enzyme activity of mitochondrial trifunctional protein is not altered by lysine acetylation or lysine succinylation.

open access: yesPLoS ONE, 2021
Mitochondrial trifunctional protein (TFP) is a membrane-associated heterotetramer that catalyzes three of the four reactions needed to chain-shorten long-chain fatty acids inside the mitochondria.

Cycvalone in the synthesis of nitrogen-, oxygen-containing heterocycles [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Химия. Биология. Экология, 2023
Cycvalone is an analogue of curcumin (EE conformation), exhibits a wide range of biological activity (antioxidant, hepatoprotective, membrane stabilizing, anti-ulcer) and is used in medical practice as a choleretic.

The effect of acylation with fatty acids and other modifications on HLA class II:peptide binding and T cell stimulation for three model peptides. [PDF]

open access: yesPLoS ONE, 2018
Immunogenicity is a major concern in drug development as anti-drug antibodies in many cases affect both patient safety and drug efficacy. Another concern is often the limited half-life of drugs, which can be altered by different chemical modifications ...

Pharmacological Activities and Chemical Stability of Natural and Enzymatically Acylated Anthocyanins: A Comparative Review

open access: yesPharmaceuticals, 2023
Anthocyanins (ANCs) are naturally occurring water-soluble pigments responsible for conferring red, blue, and purple colors to fruits, vegetables, flowers, and grains. Due to their chemical structure, they are highly susceptible to degradation by external

SIRT6 regulates Ras-related protein R-Ras2 by lysine defatty-acylation

open access: yeseLife, 2017
The Ras family of GTPases are important in cell signaling and frequently mutated in human tumors. Understanding their regulation is thus important for studying biology and human diseases.

S-acylation by ZDHHC20 targets ORAI1 channels to lipid rafts for efficient Ca2+ signaling by Jurkat T cell receptors at the immune synapse

open access: yeseLife, 2021
Efficient immune responses require Ca2+ fluxes across ORAI1 channels during engagement of T cell receptors (TCR) at the immune synapse (IS) between T cells and antigen presenting cells. Here, we show that ZDHHC20-mediated S-acylation of the ORAI1 channel
