Ethylene-regulated dimeric ETR1 kinase reveals multi-site EIN2 docking targeted by peptides that delay climacteric ripening
Ethylene receptors are ER membrane histidine kinases that repress ethylene responses, and the central transducer ETHYLENE INSENSITIVE 2 (EIN2) docks to receptors through its C-terminal tail. Here we express full-length Arabidopsis ETR1 in Pichia pastoris and show that ethylene selectively suppresses the autokinase acti...
