CC -!- FUNCTION: Accepts the ubiquitin from the E1 complex and catalyzes its
CC covalent attachment to other proteins. {ECO:0000269|PubMed:16339806}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-L-cysteine +
CC [E2 ubiquitin-conjugating enzyme]-L-cysteine = [E1 ubiquitin-
CC activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-
CC conjugating enzyme]-L-cysteine.; EC=2.3.2.23;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00388, ECO:0000255|PROSITE-
CC ProRule:PRU10133};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC -!- TISSUE SPECIFICITY: Expressed in all tissues examined. Lower levels
CC found in leaves. {ECO:0000269|PubMed:8790283}.
CC -!- INDUCTION: Not induced by heat shock. {ECO:0000269|PubMed:8790283}.
CC -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
