Nt-acetylation-independent turnover of SQUALENE EPOXIDASE 1 by Arabidopsis DOA10-like E3 ligases [PDF]
, 2023 The acetylation-dependent (Ac/)N-degron pathway degrades proteins through recognition of their acetylated N-termini (Nt) by E3 ligases called Ac/N-recognins. To date, specific Ac/N-recognins have not been defined in plants.

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]
, 2003 Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

Temperature adaptation of DNA ligases from psychrophilic organisms [PDF]
, 2019 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 ...

Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity
Biomolecules, 2022 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 ...

Regulation of SCF Ubiquitin Ligases by Jab1/Csn5 and the Cop9 Signalosome [PDF]
, 2006 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 ...

New classes of E3 ligases illuminated by chemical probes [PDF]
, 2022 Specificity in the ubiquitin system depends on E3 ligases, largely belonging to a handful of families discovered more than a decade ago. However, the last two years brought a quantum leap in the identification and/or mechanistic characterization of ...

A capsid-encoded PPxY-motif facilitates adenovirus entry. [PDF]
, 2010 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
Mediators of Inflammation, 2020 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).
