FunctionMevalonate kinase (MK) is the first enzyme in the mevalonate pathway which synthesizes sterol isoprenoids like cholesterol and non-sterol isoprenoids like ubiquinone[1]. MK catalyzes the conversion of mevalonate to 5-phosphomevalonate. See also Mevalonate pathway DiseaseMutations in MK resulting in MK deficiency cause hyperimmunoglobulinenemia D, a type of severe early-onset colitis, characterized by abdominal pain, diarrhea and vomiting[2]. RelevanceStructural highlightsThe 3D structure of MK complex with mevalonate shows the enzyme composed of : The N-terminal and the C-terminal. The mevalonate binds in a between the 2 domains forming [3]. Water molecules are shown as red spheres. 3D structures of mevalonate kinaseUpdated on 05-May-2025 2r3v - hMK - human 2r42 - rMK + farnesyl thiopyrophosphate- rat
