Evaluation of the Energetics of the Concerted Acid-Base Mechanism in Enzymatic Catalysis:The Case of Ketosteroid Isomerase
Energetics Concerted Acid-Base Mechanism Enzymatic Catalysis Ketosteroid Isomerase
2016/5/25
Structures of enzymes invariably reveal the proximity of acidic and basic residues to reactive sites on the substrate, so it is natural and common to suggest that enzymes employ concerted mechanisms t...

Michaelis-Menten Equation and Detailed Balance in Enzymatic Networks
Michaelis-Menten Equation Detailed Balance Enzymatic Networks
2014/9/24
Many enzymatic reactions in biochemistry are far more complex than the celebrated MichaelisMenten scheme, but the observed turnover rate often obeys the hyperbolic dependence on the substrate concent...
Correlation analysis of enzymatic reaction of a single protein molecule
Autocorrelation continuous time Markov chain fluorescence intensity Michaelis-Mente nmodel stochastic network model single-molecule experiment turnover time
2012/11/23
New advances in nano sciences open the door for scientists to study biological processes on a microscopic molecule-by-molecule basis. Recent single-molecule biophysical experiments on enzyme systems, ...
Analysis of noise-induced bistability in Michaelis Menten single-step enzymatic cycle
noise-induced bistability Michaelis Menten single-step enzymatic cycle
2011/8/11
Abstract: In this paper we study noise-induced bistability in a specific circuit with many biological implications, namely a single-step enzymatic cycle described by Michaelis Menten equations with qu...
Role of water in the enzymatic catalysis: study of ATP + AMP -> 2ADP conversion by adenylate kinase
enzymatic catalysis ATP + AMP -> 2ADP conversion
2011/1/6
The catalytic conversion ATP + AMP -> 2ADP by the enzyme adenylate kinase (ADK) involves the binding of one ATP molecule to the LID domain and one AMP molecule to the NMP domain. The latter is followe...
Determination of Urea in Serum Based on the Combination of an Enzymatic Reaction with Immobilized Urease and Ion Chromatographic Analysis
Determination Serum Based Combination Immobilized Urease Ion Chromatographic Analysis
2010/9/15
A quantitative method for the determination of urea in serum was studied. An ion chromatograph (IC) with a conductivity detector was used in this method, where the chromatograph was modified by placin...
Antioxidative Activities of Hydrolysates from Duck Egg White Using Enzymatic Hydrolysis
Duck Egg White Hydrolysis Antioxidant Activities
2016/5/3
Duck egg white (DEW) hydrolysates were prepared by five enzymes (papain, trypsin, chymotrypsin, alcalase, and flavourzyme) and their antioxidant activities investigated in this study. DEW hydrolyzed w...
