三甲基赖氨酸羟化酶(TMLH)是一种非血红素铁(II)和2-氧葡萄糖酸盐依赖的加氧酶,在肉毒碱生物合成的第一步催化l -三甲基赖氨酸中未活化的C-H键的C-3羟基化。对三甲基赖氨酸类似物作为人TMLH底物的研究表明,该酶可以羟化除天然l -三甲基赖氨酸以外的底物。
Trimethyllysine hydroxylase (TMLH) is a non-haem Fe(II) and 2-oxoglutarate dependent oxygenase that catalyses the C-3 hydroxylation of an unactivated C-H bond in L-trimethyllysine in the first step of carnitine biosynthesis. The examination of trimethyllysine analogues as substrates for human TMLH reveals that the enzyme does hydroxylate substrates other than natural L-trimethyllysine.
