2,3-二羥基異戊酸是支鏈氨基酸合成途徑的一個中間代謝產(chǎn)物，是合成纈氨酸和異亮氨基酸代謝途徑的中間代謝產(chǎn)物，本產(chǎn)品為生物合成方法生產(chǎn)獲得。2,3-Dihydroxy-isovalerate is an intermediate in valine, leucine and isoleucine biosynthesis. The pathway of valine biosynthesis is a four-step pathway that shares all of its steps with the parallel pathway of isoleucine biosynthesis. These entwined pathways are part of the superpathway of leucine, valine, and isoleucine biosynthesis , that generates not only isoleucine and valine, but also leucine. 2,3-Dihydroxy-isovalerate is generated from 3-Hydroxy-3-methyl-2-oxobutanoic acid via the enzyme ketol-acid reductoisomerase (EC 1.1.1.86) then it is converted to 2-Oxoisovalerate via the dihydroxy-acid dehydratase (EC:4.2.1.9).
