An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process.What is enzyme in biology?An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a...
What are enzymes? Where would you find them? What are their functions? Give a specific example. What happens to an enzyme during a chemical reaction? What are enzymes? What role do they play in biological and chemical reactions? What do enzymes have that determine their function?
An enzyme activity specifically active on nitrous acid-treated DNA was found in an extract of Escherichia coli. The enzyme acts on both double- and single-stranded DNAs, treated with nitrous acid, in the presence of EDTA, although the former DNA is a better substrate. Evidence is presented ...
The reductive enzyme thioredoxin 1 acts as an oxidant when it is exported to the Escherichia coli periplasm - Debarbieux, Beckwith - 1998 () Citation Context ...using a signal sequence to thioredoxin 1, we showed that the protein can be exported to the periplasm, where it is able to ...
53 Furthermore, structural data (Jackson and references therein) showed that the side chain of C360 rotates in and out of the active site as a function of the ligation state of the enzyme, with the residue being oriented inside the active site when the product is bound. This observation ...

enzyme (Km), as well as the substrate intake (Kcat). Enzyme reactions take place at punctual pH, known as optimum, where the highest enzyme activity (Vmax) is presented, and above or below it, the reaction rate decreased (Fig. 34.2A). Slight changes in pH values modify the ionic ...
After glucose metabolism, dietary carbohydrates produce energy and organic acids as metabolic by-products50. The acid-producing activity ofS. mutansis not only a critical factor contributing to its pathogenicity but also a crucial characteristic leading to dental caries. Bacteria enolase, an enzyme enc...

Enzyme synthesis refers to the process where the presence of certain substances, such as substrates or hormones like steroids and thyroid hormones, triggers the production of enzymes in a cell. These newly synthesized enzymes can be further activated by other types of hormones like polypeptides. ...
