LipCo biosynthesis in humans depends exclusively on a de novo pathway involving LIPT2, LIAS, and LIPT1. In this work authors present structures of LIAS captured in multiple catalytic states, revealing critical conformational changes associated with the reaction. The structures of the LIAS–Hpro complex define molecular interactions essential for complex formation. These structures enabled the mapping of amino acid changes associated with non-ketotic hyperglycemia.
