We are interested in finding an effective and the efficient way to purify horseradish peroxidase for a biochemistry enzyme purification and characterization lab. Horseradish peroxidase (HRP) is an enzyme found in the roots of horseradish plants and is a very common plant peroxidase…
With rising climate concerns, many are looking to biofuels to ease our carbon footprint. As of now, current biofuels are inefficient—for example, byproducts of corn ethanol release a similar amount of greenhouse gases as fossil fuels…
The Earth has an abundance of microbial communities; however, little is known about the diversity and quantity of these microbes. Knowing the quantity of each microbe in a sample of environmental DNA may be able to tell one about the overall health of the soil and the systems around it…
In _Escherichia coli_, fumarate and nitrate reduction regulator (FNR) is a transcription factor protein that allows the organism to switch between aerobic and anaerobic respiration…
Sourdough starters are leavening agents made from flour and water that have naturally occurring bacteria and yeast to make dough rise. These microorganisms also give sourdough bread its unique flavors…
Ammonia oxidizing bacteria play a crucial role in the nitrogen cycle, catalyzing the conversion of ammonia into nitrates and nitrites. This enzymatic activity is mediated by a key gene known as _amoA_, which encodes for the ammonia monooxygenase enzyme…
The FNR (fumarate and nitrate reductase) transcription factor is an important regulator in the switch between anaerobic and aerobic respiration in _Escherichia coli_. The switch is mediated by a [4Fe-4S]2+ cluster that is ligated by 3 cysteine residues within the N-terminus of the protein…
FNR is a transcription factor and regulatory protein present in _Escherichia coli_. Its function is to switch between anaerobic and aerobic respiration…
