Protein lipidation dramatically affects protein structure, localization, and trafficking via remodeling protein-membrane and protein-protein interactions through hydrophobic lipid moieties. Understanding the biosynthesis of lipidated proteins, whether natural ones or mimetics, is crucial for reconstructing, validating, and studying the molecular mechanisms and biological functions of protein lipidation. In this Perspective, we first provide an overview of the natural enzymatic biosynthetic pathways of protein lipidation in mammalian cells, focusing on the enzymatic machineries and their chemical linkages. We then discuss strategies to biosynthesize protein lipidation in mammalian cells by engineering modification machineries and substrates. Additionally, we explore site-specific protein lipidation biosynthesis via enzyme-mediated ligations and primarily through genetic code expansion strategies. We also discuss the use of small molecule tools to modulate the process of protein lipidation biosynthesis. Finally, we provide concluding remarks and discuss future directions for the biosynthesis and applications of protein lipidation.

Background: Fracture disrupts the integrity and continuity of the bone, leading to symptoms such as pain, tenderness, swelling, and bruising. Rhizoma Musae is a medicinal material frequently utilized in the Miao ethnic region of Guizhou Province, China. However, its specific mechanism of action in treating fractures remains unknown.

Background: Overactive bladder (OAB) is a common disorder, particularly in women, and its symptoms, including urgency, frequency, and nocturia, can significantly affect quality of life. The cardiometabolic index (CMI) is a novel metabolic risk indicator that has been receiving more attention lately. This study investigated the association between CMI and OAB in adult women.

Ferroptosis is a unique cell death mode that relies on iron and lipid peroxidation (LPO) and is extensively utilized to treat drug-resistant tumor. However, like the other antitumor model, requirement of oxygen limited its application in treating the malignant tumors in anaerobic environments, just as photodynamic therapy, a very promising anticancer therapy. Here, we show that an iridium(III) complex (Ir-dF), which was often used in proton-coupled electron transport (PCET) process, can induce efficient cell death upon photo irradiation, which can be effectively protected by the typical ferroptosis inhibitor Fer-1 but not by the classic iron chelating agents and ROS scavengers.

Disproportion between reactive oxygen species (ROS) production and the body's antioxidant system can cause oxidative stress, which is considered a common denominator in various pathological conditions, including cardiovascular diseases, aging, and cognitive disorders. The generation of free radicals, which occurs through partial reduction of oxygen, can quickly overwhelm the endogenous antioxidant system capacity of the cell. This causes lipid, protein, DNA and RNA damage, inflammation, and overall cell degeneration, which can be mitigated by various antioxidants.

It includes type heterozygous familial hyperlipidemia (heterozygous familial hypercholesterolemia). HeFH is mainly caused by mutations in the LDLR, APOB, and PCSK9 genes and is characterized by elevated plasma low-density lipoprotein cholesterol levels.
