The invention relates to a cell which has been genetically modified so as to be capable of producing more 2-hydroxyisobutyric acid or more polyhydroxyalkanoates containing 2-hydroxyisobutyric acid monomer units than its wild type, characterized in that 2-hydroxyisobutyric acid or polyhydroxyalkanoates containing 2-hydroxyisobutyric acid monomer units are produced via acetoacetyl-coenzyme A as intermediate and 3-hydroxybutyryl-coenzyme A as precursor.
本发明涉及一种经过
基因修饰的细胞,与野生型相比,该细胞能够产生更多的 2-羟基
异丁酸或含有 2-羟基
异丁酸单体单元的更多的聚羟基烷酸酯,其特征在于 2-羟基
异丁酸或含有 2-羟基
异丁酸单体单元的聚羟基烷酸酯是通过乙酰乙酰
辅酶 A 作为中间体和 3-羟基丁酰
辅酶 A 作为前体产生的。
