Temperature adaptation of DNA ligases from psychrophilic organisms [PDF]
DNA ligases operating at low temperatures have potential advantages for use in biotechnological applications. For this reason, we have characterized the temperature optima and thermal stabilities of three minimal Lig E-type ATP-dependent DNA ligase ...

Regulation of SCF Ubiquitin Ligases by Jab1/Csn5 and the Cop9 Signalosome [PDF]
SCF ubiquitin ligases regulate the ubiquitin-dependent proteolysis of a myriad of substrate proteins, including p27, Cyclin E, and IkBa. To further gain insight into SCF regulation and function, we purified SCF from mammalian cells and found the Cop9 ...

Ligandability of E3 Ligases for Targeted Protein Degradation Applications
Targeted protein degradation (TPD) using proteolysis targeting chimeras (PROTACs) and molecular glue degraders has arisen as a powerful therapeutic modality for eliminating disease-causing proteins from cells.

Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity
In recent years, researchers have leveraged the ubiquitin-proteasome system (UPS) to induce selective degradation of proteins by E3 ubiquitin ligases, which has great potential as novel therapeutics for human diseases, including cancer and ...

A capsid-encoded PPxY-motif facilitates adenovirus entry. [PDF]
Viruses use cellular machinery to enter and infect cells. In this study we address the cell entry mechanisms of nonenveloped adenoviruses (Ads). We show that protein VI, an internal capsid protein, is rapidly exposed after cell surface attachment and ...

Role of RING-Type E3 Ubiquitin Ligases in Inflammatory Signalling and Inflammatory Bowel Disease
Ubiquitination is a three-step enzymatic cascade for posttranslational protein modification. It includes the ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligase (E3).

Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA
Protein modification by the small ubiquitin-like modifier (SUMO) plays an important role in multiple plant processes, including growth, development, and the response to abiotic stresses.

Characterisation of ATP-Dependent Mur Ligases Involved in the Biogenesis of Cell Wall Peptidoglycan in Mycobacterium tuberculosis [PDF]
ATP-dependent Mur ligases (Mur synthetases) play essential roles in the biosynthesis of cell wall peptidoglycan (PG) as they catalyze the ligation of key amino acid residues to the stem peptide at the expense of ATP hydrolysis, thus representing ...

Developing as assay to screen inhibitors for various ATP-dependent ligases [PDF]
DNA ligases (EC.6.5.1.1) are key enzymes that catalyze the formation of phosphodiester bonds at single-stranded or double-stranded breaks between adjacent 5’-PO4 and 3’-OH groups of DNA. These enzymes are essential guardians of genomic integrity and have
