[求助]
求一句英文潤(rùn)色?(生物專(zhuān)業(yè))
|
|
在有前體積累的菌種里增加轉(zhuǎn)氨酶的酶活(轉(zhuǎn)氨酶催化異亮氨酸細(xì)胞內(nèi)合成的最后一步反應(yīng)),此舉并沒(méi)有促使異亮氨酸的外排,這說(shuō)明了菌種的改良策略很不在合成途徑,而在于將已經(jīng)合成的異亮氨酸轉(zhuǎn)運(yùn)出胞外。 譯文如下: 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. 希望有蟲(chóng)友幫忙看看這個(gè)句子,寫(xiě)的很長(zhǎng),但是不知是否有錯(cuò)誤。 |

唉,姐你湊合看看吧。坐等高人應(yīng)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. |
