Post-translational Regulation of ACO An in vitro phosphorylation assay using protein extracts of pre- and post-climacteric apple fruit and an ectopically expressed His-tagged Md ACO1 (MDP0000195885) hinted for the first time that ACO protein-protein interactions could exist (Matarasso et al., 2005), and the strongly conserved C28 as a key residue in the active site of this protease ( in silico predictions based on sequence similarity, other motifs for ACO protein-protein interactions, serine/threonine kinases, tyrosine kinases, and glycosylation were identified ( Arabidopsis ACO2 (AT1g62380) was identified as a target in a broad proteomics screen that characterized stress-induced protein S -glutathionylation, suggesting that ACO2 is post-translationally modified by glutathionylation ( Another thiol-residue modification of ACO was discovered in a large cysteine S-sulfhydration screen in Arabidopsis, which showed that ACO4 can get sulfhydrated ( 2 S production increases in stomata upon a prolonged ethylene treatment, and that this leads to the S-sulfhydration of C60 (equivalent to C63 of At ACO2) of Sl ACO1 (Solyc07g049530) and Sl ACO2 (Solyc12g005940)
That last qualifier matters: an open-label study with exploratory endpoints generates encouraging signals and answers a specific dosing question, but it cannot substitute for the randomized, controlled cirrhosis-outcome trial now underway in Phase 3

However, the lack of diarrhea or Shiga toxin exposure combined with the patients background, like age and history of post-COVID-19 recovery, made typical HUS unlikely
