How is the activity of an enzyme is regulated? How does pH affect an enzyme? How does substrate concentration affect the speed of enzymatic reactions? What are some factors that affect enzyme activity? How does changing the pH affect the rate of enzyme activity?
How does a change in pH alter the activity of an enzyme? Describe the structure and function of enzymes, and indicate how temperature and pH affect the rate of enzyme reactions. How do environmental effects influence enzyme function? How does substrate concentration affect enzyme activity?
Within a narrow pH range, structural and morphological changes in enzymes and substrates may be reversible. However, if the pH level changes substantially, the enzyme and substrate may be denatured. There will be no reaction since the enzyme and the substrate do not recognize each other. Optimal...

The media used were a source of minerals in amounts depending on the substrate: YP media contained (amount in mg/L): 8.49; 863; 6.16; 488; 230, and 254, while DPJW contained: 23.7; 5907; 259; 25.1; 419, and 732 of elements: Ca, K, Mg, Na, P, and S, respectively. The ...
enolase, an enzyme encoded by the geneeno, is a primary component of the phosphotransferase system, which is responsible for glucose uptake51. Through the rapid catalytic activity of lactate dehydrogenase (LDH), a protein encoded by theldhgene,S. mutansUA159 ferments glucose into organic acids...
In general, the holoenzyme dimer resembles a "U" shape, with each side constituting a monomer containing both recognition and catalytic domains with an overlapping bridging domain at the bottom. The DNA is bound between the two subunits. FokI, the most studied Type IIs enzyme, appears to exist...
