E3 ligases Enzymes that attach ubiquitin or ubiquitin-like proteins to target proteins. Rights and permissions Reprints and permissions About this article Cite this article Vos, S., Tretter, E., Schmidt, B. et al. All tangled up: how cells direct, manage and exploit topoisomerase function. Nat...
Both are non-essential aminoacyl-tRNA-dependent ligases that add amino acids to the lysine in the third-position of the pentapeptide stem of lipid II [72]. Particularly, MurM can attach either L-serine or L-alanine at the first position of the dipeptide bridge. MurM from penicillin-...
Other approaches, that do not require crosslinking of RNPs, use proximity proteomics to identify RBP-RNA interactions in live cells. These approaches rely on ‘promiscuous’ biotin ligases that are able to label preferentially proteins that are within 20 nm of distance with biotin [226,227]. ...
LOV domains were first identified in plant phototropins (LOV1 and LOV2) but also found conjugated to some regulatory proteins of circadian rhythms, phosphodiestrases, kinases, ubiquitin ligases, and DNA-binding proteins (Crosson et al., 2003). The first sLOVs identified were found ...
Under basal conditions, E3 ubiquitin ligases contribute to maintaining low levels of NLRP3. For instance, F-box/LRR-repeat protein 2 binds NLRP3 at W73 and leads to its degradation through ubiquitination of K689 [91]. Tripartite motif-containing protein 31 (TRIM31) also limits NLRP3 abundance...
The RNA world hypothesis has since triggered research on ribozymes [21–28] to demonstrate various enzymatic activities, including ligases, distributive (but non-processive) RNA-polymerases, nucleases, aminoacyl tRNA synthetases and other types of activities by polynucleotides of up to 300 bases in ...
