求一句英文润色?(生物专业)

在有前体积累的菌种里增加转氨酶的酶活(转氨酶催化异亮氨酸细胞内合成的最后一步反应),此举并没有促使异亮氨酸的外排,这说明了菌种的改良策略很不在合成途径,而在于将已经合成的异亮氨酸转运出胞外。 译文如下: L-isoleucine excretion of the strains with accumulations of precursors is not affected after increasing transaminase(catalyses the last step of isoleucine biosynthetic pathway) activity. It indicated that the strategy of strain's improvement is most probably not the biosynthetic reaction, but rather the secretion of the synthesized isoleucine from the cell. 希望有虫友帮忙看看这个句子,写的很长,但是不知是否有错误。 |

唉,姐你凑合看看吧。坐等高人应助。 It is known that transaminase catalyses the last step of isoleucine biosynthetic pathway. However, increasing transaminase activity does not affect the L-isoleucine excretion from the strains with accumulative precursors. This result indicates that the strategy of strain's improvement probably does not rely on the biosynthetic reaction, but rather the secretion of the synthesized isoleucine from the cell. |
