Mutations in the human HPD gene (encoding 4-hydroxyphenylpyruvic acid dioxygenase) cause hereditary tyrosinemia type 3 (HT3). We deleted the Aspergillus nidulans homologue (hpdA). We showed that the mutant strain is not able to grow in the presence of phenylalanine and that it accumulates increased concentrations of tyrosine and 4-hydroxyphenylpyruvic acid, mimicking the human HT3 phenotype.
人类HPD基因(编码4-羟基苯丙酮酸双加氧酶)的突变会导致遗传性III型酪氨酸血症(HT3)。我们删除了构巢曲霉的同源基因(hpdA)。我们发现,该突变菌株在苯丙氨酸存在的情况下无法生长,并且积累了浓度升高的酪氨酸和4-羟基苯丙酮酸,模拟了人类HT3的表型。
