Covalent attachment of small ubiquitin-like modifier (SUMO) to proteins regulates multiple processes in the eukaryotic cell. In numerous cases sumoylation is facilitated by protein inhibitor of activated STAT (PIAS) proteins, characterized by the presence of a SP-RING domain related to the RING finger of many ubiquitin E3 ligases. The importance of SP-RING relies on its capacity to bind the E2 enzyme of the pathway. Additional domains may participate in SUMO ligase function and target selection…

Functional characterization of DnSIZ1, a SIZ/PIAS-type SUMO E3 ligase from Dendrobium
TLDR
The results suggest that DnSIZ1 is a functional homolog of the Arabidopsis SIZ1 with SUMO E3 ligase activity and may play an important role in the regulation of Dendrobium stress responses, flowering and development.
Structural and functional studies of SIZ1, a PIAS-type SUMO E3 ligase from Arabidopsis
TLDR
It is established that the diverse properties characteristic of SIZ1 are associated with specific domains and that they can be separated.
Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA
TLDR
This review explores the biological functions of plant SUMO E3 ligases in relation to their molecular activities and domains and explores evidence suggesting a connection between certainsumO E 3 ligases and DNA that contributes to gene expression regulation.
Identification and molecular properties of SUMO-binding proteins in Arabidopsis
TLDR
The results suggest specific interactions between sumoylation targets and particular sumoylated enzymes in animals and yeasts.

Investigation of mutants and substrates of the Arabidopsis SUMO conjugating system
TLDR
The broad variety of aspects discussed in this work emphasizes the importance and complexity of Arabidopsis SUMOylation and indicates that the understanding of this modification in plants can only be achieved by further studies and identification of in vivo SUMO substrates.
Reconstitution of Arabidopsis thaliana SUMO pathways in E. coli: functional evaluation of SUMO machinery proteins and mapping of SUMOylation sites by mass spectrometry.
TLDR
Reconstituted the Arabidopsis thaliana SUMOylation cascade in Escherichia coli will be a powerful tool for elucidation of the role of SUMoylation and of the biochemical and structural features ofsumOylated proteins in plants.
SUMO modification of LBD30 by SIZ1 regulates secondary cell wall formation in Arabidopsis thaliana
TLDR
A mechanism by which sumoylation of LBD30, mediated by SIZ1, regulates SCW formation in A. thaliana is presented.
SUMO and SUMOylation in plants
TLDR
Results of recent insights into the role of sumoylation in plants are discussed and further SUMO noncovalent binding appears to have function in other model organisms and SUMO interacting proteins in plants will be of interest to plant biologists who dissect the dynamic function of SUMO.

PIAS Proteins Modulate Transcription Factors by Functioning as SUMO-1 Ligases
TLDR
The results imply that PIAS proteins function as SUMO-1-tethering proteins and zinc finger-dependent E3 SUMO protein ligases, and these properties are likely to explain their ability to modulate the activities of various transcription factors.
SUMO-Conjugating and SUMO-Deconjugating Enzymes from Arabidopsis1
TLDR
This work reconstituted its SUMOylation cascade in vitro and tested the capacity of this system to conjugate the Arabidopsis SUMO isoforms AtSUMO1, 2, and 3 to the model substrate ScPCNA from yeast (Saccharomyces cerevisiae) using the known SUMO isopeptidases ScULP1, XopD, and ESD4 as reference enzymes.
The Small Ubiquitin-like Modifier (SUMO) Protein Modification System in Arabidopsis
TLDR
Taken together, the SUMO conjugation system appears to be a complex and functionally heterogeneous pathway for protein modification in plants with initial data indicating that one important function may be in stress protection and/or repair.
The Small Ubiquitin-like Modifier-1 (SUMO-1) Consensus Sequence Mediates Ubc9 Binding and Is Essential for SUMO-1 Modification*
TLDR
It is demonstrated that the SUMO-1-CS is a major determinant of Ubc9 binding and SUMo-1 modification, and mutating residues in thesumO- 1-CS abolishes both Ubc 9 binding and substrate modification.
Yeast Ull1/Siz1 Is a Novel SUMO1/Smt3 Ligase for Septin Components and Functions as an Adaptor between Conjugating Enzyme and Substrates*
TLDR
In this system, Ull1 is additionally required as well as E1 (Sua1·Uba2 complex), E2 (Ubc9), and ATP for the conjugation of a septin component (Cdc3) using purified recombinant proteins.
Genetic Analysis of SUMOylation in Arabidopsis: Conjugation of SUMO1 and SUMO2 to Nuclear Proteins Is Essential1[OA]
TLDR
It appears that SIZ1-mediated conjugation of SUMO1 and SUMO2 to other intracellular proteins is essential in Arabidopsis, possibly through stress-induced modification of a potentially diverse pool of nuclear proteins.
The Plant Homeodomain Fingers of Fission Yeast Msc1 Exhibit E3 Ubiquitin Ligase Activity*
TLDR
Deletion of msc1 confers complete suppression of the slow growth phenotype, UV and hydroxyurea sensitivities of an rhp6 deletion strain and restores deficient histone H3 methylation observed in the rhp 6Δ mutant, suggesting that the target of the E3 ubiquitin ligase activity of Msc1 is likely to be a chromatin-associated protein.
