Rice	Os02g0261100	E2 conjugating enzyme that associates with the E3 ubiquitin- protein ligase EL5 to mediate ubiquitination of target proteins.	EL5, a rice N-acetylchitooligosaccharide elicitor-responsive RING-H2 finger protein, is a ubiquitin ligase which functions in vitro in co-operation with an elicitor-responsive ubiquitin-conjugating enzyme, OsUBC5b.; 2002; DOI: 10.1046/j.1365-313x.2002.01299.x; PMID: 12028574; https://pubmed.ncbi.nlm.nih.gov/12028574/
