The glycolytic pathway contains one oxidative step . 糖酵解途径只有一个氧化反应。
2.
The global regulator csra of e . coli is a specific mrna - binding protein . csra negatively regulates several metabolic pathways that are induced post - exponentially , including glycogen biosynthesis , gluconeogenesis , and glycogen catabolism ; positively controls gene expression within the glycolytic pathway ; and also csra modulates the levels of enzymes that participate directly in pep metabolism Csra是整体调控网络的调控基因，可负调控指数生长后期诱导的一些代谢途径，包括糖原的生物合成、糖原的分解代谢、糖异生，而对糖酵解的一些重要基因的表达则执行正调控功能， csra也调控直接参与pep代谢的三个酶的活性水平。
