The clarified supernatant was directly purified using a Ni-NTA Spin Column according to instructions supplied by the manufacturer (QIAGEN). Briefly, after washing the column with wash buffer1 (50 mM NaH2PO4 pH 7.5), the supernatant was loaded onto the column, and the column was washed with wash buffer 2 (50 mM NaH2PO4 pH 7.5, 500 mM NaCl, 0.025 Triton X-100 and 20 mM imidazole). The integrase protein was eluted from the column using elution buffer (50 mM NaH2PO4 pH 7.5, 500 mM NaCl, 0.025 Triton

ensure amplification (Figure 4). The PCR fragment was purified using the Quick-Start Protocol for the QIAquick PCR Purification Kit. After the purification of the PCR fragment, a digest of the M. Xanthus PCR fragment into the PET45 plasmid using enzymes KPN1 and HINDIII was performed.

An enzyme is a “macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction,” (Campbell Biology, 68). There are many different enzymes that have varying effects on reactions. Catalase, “an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen,” is the primary enzyme that effects hydrogen (Encyclopedia Britannica). In this experiment, the goal is to test how three different locations where these enzymes can be

Enzymes are catalytic proteins that accelerate the rate of biological reactions while experiencing no permanent chemical modification as a result of their participation in a reaction. In order to initiate a reaction from a reactant called a substrate to a product, a certain amount of energy, otherwise known as the activation energy, is required. An enzyme functions by lowering the required activation energy (which is usually provided by heat), thus, expediting the reaction. Many chemical reactions

the membrane and purely physically adsorbed lipase. Therefore, the lipase can be easily flushed away under a high shear force condition. In contrast, the desorption ratio remained no more than 10% after crosslinking, owing to the resolution of the enzyme leakage problem during the operation. --Figure 7-- Optimization of operating condition of EMBR For obtaining the best performance of EMR, an appropriate operating condition should be selected. To optimize the operating condition of EMR, RSM was applied

Hypothesis Introduction: The Succinate Dehydrogenase (SDH) is an enzyme that's found in the inner mitochondrial membrane (the powerhouse of the the cell). The mitochondria has all the equipment needed for the cell and its components with energy to carry out cellular processes. The SDH enzyme is the only one that participates in both the Citric acid cycle (krebs cycle) and the electron transport chain (ETC). We are manipulating the SDH enzyme using the reagent Oxaloacetate, also known as oxaloacetic acid

Starch needs to be broken down to glucose in order for fermentation to occur. There is no enzyme in this beaker to break down the starch. Beaker 3 – CO2 will be produced the second fastest. As amylase is in this beaker, starch can be broken down to its monomer unit but it will not be as fast as Beaker 1 since the latter already contains its

concentration (Xia et al, 2016). Every one of these 3 elements are essential for the survival of yeast, which will now have the opportunity to experience alcoholic fermentation. According to research that has been done to decide the ideal pH value of which enzymes are the most active. The most elevated rate of yeast fermentation, followed by the amount of ethanol produced is accomplished at a pH 5 (Deesuth, Laopaiboon, and Laopaiboon, 2016). An experiment conducted by Li Wang, Robert Knowles, and Shuzer Tanoka

strongly involved in eukaryotic cellular functions and are found in copious amounts. Certain protein ligases attach ubiquitin to proteins, which degrades them and interferes with normal cellular functions. The discovery of a specific de-ubiquitinating enzyme (HAUSP/USP7) found in humans was due to its
