4.2.1.3 | acetylation |
in vitro chemical acetylation with either acetic anhydride or acetyl-CoA results in increased aconitase activity that is reversed with SIRT3 treatment. Lysine residues K31, K138, K144, K401, K549, K689, K700, K701, and K723 represent the most responsive sites. A high fat diet (60% kcal from fat) also shows significantly increased mitochondrial aconitase activity without changes in protein level and produces increased aconitase acetylation at multiple sites |

4.2.1.3 | phosphoprotein |
aconitase is phosphorylated on serine residues. Increase in extensor digitorum longus muscle enzyme activity upon repeated contraction is inhibited by cyclosporin A, an inhibitor of the protein phosphates calcineurin |

mechanism controlling IRP1 activity at the level of its stability can be phosphorylation of Ser138, Ser138, Ser711, and flanking sequences are highly conserved |

4.2.1.3 | phosphoprotein |
S711 of IRP1 is phosphorylated by proteinkinase C in vitro and in vivo in human HEK cells. Aconitase activity of the S711 phosphomimetic mutants is preferentially inhibited in the citrate mode of aconitase function. The substitution of phosphomimetic amino acids for S711 fails to affect the RNA-binding affinity of IRP1 |
