1 The Arabidopsis RING-type E3 ligase XBAT32 mediates the proteasomal degradation of the ethylene biosynthetic enzyme, 1-aminocyclopropane-1-carboxylate synthase 7. ethylene 1-amino-cyclopropane-1-carboxylate synthase 7 Arabidopsis thaliana
2 Previous work has suggested that XBAT32 modulates ethylene production by ubiquitinating two ethylene biosynthesis enzymes, ACS4 (type-II isoform) and ACS7 (type-III isoform). ethylene 1-amino-cyclopropane-1-carboxylate synthase 7 Arabidopsis thaliana
3 Previous work has suggested that XBAT32 modulates ethylene production by ubiquitinating two ethylene biosynthesis enzymes, ACS4 (type-II isoform) and ACS7 (type-III isoform). ethylene 1-amino-cyclopropane-1-carboxylate synthase 7 Arabidopsis thaliana
4 Furthermore, the ethylene-related phenotypes that result from overexpression of ACS7 in wild-type plants are greatly exaggerated in xbat32-1, suggesting that XBAT32 is required to attenuate the effect of overexpression of ACS7. ethylene 1-amino-cyclopropane-1-carboxylate synthase 7 Arabidopsis thaliana
