A new shunt in the phenylalanine biosynthetic pathway to the nonproteinogenic amino acid L-3-cyclohex-2'-enylalanine was exploited in the marine bacterium Salinispora tropica by mutagenesis to allow for the genetic engineering of unnatural derivatives of the potent proteasome inhibitor salinosporamide A (2) such as antiprotealide (1).
通过诱变在热带盐孢菌中利用苯丙氨酸生物合成途径中的一个新分支,使其生成非蛋白质氨基酸L-3-环己-2'-烯基丙氨酸,从而对强效蛋白酶体抑制剂盐孢菌素A(2)的非天然衍生物(如抗蛋白酶体化合物(1))进行基因工程改造。
