酵素動力學被廣泛地運用在代謝網路和生物化學領域,尤其是大
型代謝模組的系統路徑。其中影響酵素反應速率的因素很多,例如反
應物的濃度、酵素濃度或抑制劑皆會影響。所以運用適當的演算方法
及動力學參數可以簡化計算過程,特別是在計算代謝物的濃度與通量
時。為了減輕繁複的運算過程,在我們的代謝反應模組採用通用酵素
方程式來計算。
在本論文中,結合了通用酵素方程式與中央代謝網路(AM1)的計
算方法,而AM1 它是一種在充滿甲醛的環境中生長的細菌所形成的
代謝模組,其中面對通式中的數學表達方法以及動力學參數的運算,
我們直接採用Matlab 中專門處理數學的工具來進行運算。經由模擬
之後,我們可經由實驗數據觀察動態模組的代謝物濃度及通量做穩態
分析。
我們的研究著重於通用酵素方程式演算法在Matlab 程式上的開
發與建立。在前半部我們先從AM1 的理論開始介紹,最後使用經由
運算所得知的代謝物濃度及通量模擬出系統的特徵圖形。
Enzyme dynamics is widely applied in metabolic networks and
many other biochemical fields,especially the systematic pathway is a
large scale metabolic model. There are many factors affect the catalysis of
enzyme such as concentration of reactants,enzymes and inhibitors.
Choosing suitable algorithm and kinetic parameters can simplify the
calculation process,in terms of metabolic fluxes and concentration of
metabolites.To alleviate some problems,we use generic enzymatic rate
equations form for the metabolic reactions in our model.
In this thesis, we combine generic form with the modeling of central
metabolic network AM1,a methylotrophic and environmental import
bacterium.With the explicitly mathematical representation of the
metabolic network,various kinetic parameters can be obtain via standard
mathematical tools which are usually available in Matlab. Experimental
results show that a set of steady state flux and metabolite concentrations
for the kinetic model .
Our implementation is focus on developing the Matlab program for the
generic form and In the beginning,we discussed the throry of AM1,finally
we used the a set of steady state flux and metabolite concentrations to
simulate the systematic characteristics.
