intracellular enzymes 中文意思是什麼
-
In bacterial, many enzymes compete for intracellular pep, especially the phosphotransferase system which is responsible for glucose transport in e. coli. this system uses pep as a phosphate donor and converts it to pyruvate, which is less likely to recycle back to pep
Pep和e4p是dahp合成的限制性底物，在大腸桿菌中， pep又是許多酶的競爭性底物，特別是負責葡萄糖轉運的糖磷酸基轉運系統。 -
No touches upon multiple aspects of intracellular signaling pathways such as gene activation, protein expression and activity regulation of enzymes
No參與了跨膜信號轉導的多個層面，如基因活化、蛋白質表達和酶活性的調節。 -
Several enzymes that indirectly affect pep are also regulated by csra. thus, a csra mutation not only causes a significant elevation in intracellular pep, but also breaks cellular intrinsic metabolic coordination and channel more carbon flux to phenylalanine biosynthesis
另外，一些間接影響pep的酶也被csra所調控，因此csra的敲除不但可以使細胞內的pep的量大大增加，而且打破了細胞固有的生理代謝協調，使碳代謝流盡可能多的流向苯丙氨酸的生物合成方向。 -
Enzymes are either intracellular, catalyzing reactions within the cell such as those involved in the metabolic, regulatory, signaling, or synthesis pathways ; or extracellular, circulating in the spaces between cells or in the bloodstream, where they catalyze reactions critical to the functioning of a multicellular organism
酶可以是細胞內的，催化細胞內的反應如：新陳代謝、調節、信號傳導或合成過程；或細胞外的，在細胞間或血液里循環，並在那裡催化對于多細胞生物的功能具有重要作用的反應。
