G-butirobetain dioksigenaza (EC 1.14.11.1, alfa-butirobetainska hidroksilaza, gama-butirobetainska hidroksilaza, butirobetainska hidroksilaza) je enzim sa sistematskim imenom 4-trimetilamoniobutanoat,2-oksoglutarat:kiseonik oksidoreduktaza (3-hidroksilacija).[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

4-trimetilamoniobutanoat + 2-oksoglutarat + O2 {\displaystyle \rightleftharpoons } 3-hidroksi-4-trimetilamoniobutanoat + sukcinat + CO2

Za rad ovog enzima se neophodni Fe2+ i askorbat.[2]
