[https://www.uniprot.org/uniprot/UBC9_HUMAN UBC9_HUMAN] Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3 and SUMO4 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the help of an E3 ligase such as RANBP2 or CBX4. Can catalyze the formation of poly-SUMO chains. Necessary for sumoylation of FOXL2 and KAT5. Essential for nuclear architecture and chromosome segregation.<ref>PMID:8668529</ref> <ref>PMID:11451954</ref> <ref>PMID:15809060</ref> <ref>PMID:19744555</ref> <ref>PMID:19638400</ref> <ref>PMID:17466333</ref> <ref>PMID:20077568</ref> | |||

== Publication Abstract from PubMed == | |||
Enzymes are powerful tools for protein labelling due to their specificity and mild reaction conditions. Many protocols, however, are restricted to modifications at protein termini, rely on non-peptidic metabolites or require large recognition domains. Here we report a chemoenzymatic method, which we call lysine acylation using conjugating enzymes (LACE), to site-specifically modify folded proteins at internal lysine residues. LACE relies on a minimal genetically encoded tag (four residues) recognized by the E2 small ubiquitin-like modifier-conjugating enzyme Ubc9, and peptide or protein thioesters. Together, this approach obviates the need for E1 and E3 enzymes, enabling isopeptide formation with just Ubc9 in a programmable manner. We demonstrate the utility of LACE by the site-specific attachment of biochemical probes, one-pot dual-labelling in combination with sortase, and the conjugation of wild-type ubiquitin and ISG15 to recombinant proteins. | |||
