There is provided a method of producing at least one unsaturated amino acid from at least one amino acid comprising at least two carbonyl groups, the method comprising (a) contacting a recombinant microbial cell with a medium comprising the amino acid comprising the carbonyl groups, wherein the cell is genetically modified to comprise -at least a first genetic mutation that increases the expression relative to the wild type cell of an enzyme (E) selected from the CYP152 10 peroxygenase family, and -at least a second genetic mutation that increases the expression relative to the wild type cell of at least one NAD(P)+ oxidoreductase (E2) and the corresponding mediator protein.
提供了一种从至少含有两个羰基基团的至少一种氨基酸中生产至少一种不饱和氨基酸的方法,该方法包括(a)将重组微生物细胞与包含含有羰基基团的氨基酸的培养基接触,其中该细胞经过基因改造,包括-至少第一遗传突变,相对于野生型细胞增加从CYP152 10过氧化物酶家族中选择的酶(E)的表达,以及-至少第二遗传突变,相对于野生型细胞增加至少一种NAD(P)+氧化还原酶(E2)和相应的中介蛋白的表达。
