Working with Enzymes:  Part I -The Simple Kinetic Spectrophotometric Assay

Working with Enzymes: Part I -The Simple Kinetic Spectrophotometric Assay

At the end of my last article, I provided some practical tips and tricks for working with enzymes at the bench. Now, we’ll cover one of the cornerstone techniques of enzymology work: the enzyme assay. Starting with the simple assays and eventually working our way to the more complex, this article introduces the principles of…

Working with Enzymes: Stability, Purification and Activity

Working with Enzymes: Stability, Purification and Activity

In Part 1 of this series, we began our journey into the fascinating world of enzymology. We looked at the most basic concepts of what an enzyme is and the incredible jobs it can do. In Part 2 of “Working with Enzymes,” I will look at some things that you should keep in mind to…

So You Want to Work With Enzymes: What Is An Enzyme?

So You Want to Work With Enzymes: What Is An Enzyme?

Protein kinases and protein phosphatases phosphorylate and dephosphorylate a plethora of proteins. They are responsible for regulating the majority of cellular activities. Because of their importance, they can seem intimidating to tackle as a research project. At the end of the day however, kinases and phosphatases are- simply put- enzymes. Therefore, you can standard enzyme…

Basics of Protein Phosphorylation Part II: Tools of the Trade

Basics of Protein Phosphorylation Part II: Tools of the Trade

In the previous article in this series, we looked at the major players involved in protein phosphorylation: protein kinases, protein phosphatases, and target proteins. This time, we’ll glance over some of the tools that we can use to study various aspects of protein phosphorylation, focussing on a few I’ve personally come across. 1. Tools for…

Basics of Protein Phosphorylation Part I: Introducing the Candidates

Basics of Protein Phosphorylation Part I: Introducing the Candidates

The focus of my grad studies and postdoctoral research has been the analysis of proteins regulated by reversible protein phosphorylation. However, the number of unique facets in which protein phosphorylation can be studied is astounding, and is diverse as any niche of the biosciences. This article is the first in a series that will give…
