Ubiquitin (Ub) is a small protein that consists of 76 amino acids about 8.5 kDa. In ubiquitin
conjugation, the ubiquitin is majorly conjugated on the lysine residue of protein by Ub …

Of the three classes of enzymes involved in ubiquitination, ubiquitin-conjugating enzymes
(E2) have been often incorrectly considered to play merely an auxiliary role in the process …

All seven lysine residues in ubiquitin contribute to the synthesis of polyubiquitin chains on
protein substrates. Whereas K48-linked chains are well established as mediators of …

Protein ubiquitination, which is a major post-translational modifications that occurs in
eukaryotic cells, is involved in diverse biological processes. To date, large-scale profiling of …

The ubiquitin-proteasome system is a central mechanism for controlled proteolysis that
regulates numerous cellular processes in eukaryotes. As such, defects in this system can …

The ubiquitin-26S proteasome system is important in the quality control of intracellular
proteins. The ubiquitin-26S proteasome system includes the E1 (ubiquitin activating), E2 …

Post-translational modifications of proteins with ubiquitin (Ub) and ubiquitin-like modifiers
(Ubls), orchestrated by a cascade of specialized E1, E2 and E3 enzymes, control a wide …

Flowering time control integrates endogenous as well as environmental signals to promote
flower development. The pathways and molecular networks involved are complex and …

Cellular cross-talk between ubiquitination and other posttranslational modifications
contributes to the regulation of numerous processes. One example is ADP-ribosylation of the …

Plants, as sessile organisms, have limited means to cope with environmental changes.
Consequently, they have developed complex regulatory systems to ameliorate abiotic …
