RESEARCH: PANTOTHENATE-KINASE-SIMULATION
FOLDING PROJECT #12295 PROFILE

This project studies human enzymes that make Acetyl-CoA, a vital energy molecule. Researchers are looking at how these enzymes work and how to control them using drugs. Understanding this could lead to new treatments for heart disease and other conditions.

Note: This TLDR is a simplication and may not be 100% accurate.

These simulations are exploring the landscape of the dimer pantothenate kinase 2 and 3 from humans.

This enzyme is the rate-limiting step in the synthesis of Acetyl-CoA, and is widely expressed across many tissues.

The enzyme processes vitamin B5 (pantothenate) yielding phosphopantothenate, which is then worked up by other enzymes into Acetyl-CoA.

Acetyl-CoA binds to the same site as pantothenate, and thus prevents the enzyme from overproducing pantothenate through product inhibition.

These simulations are part of an effort to identify conformations that are important for other inhibitors of that site.

Being able to control when the enzyme is productive regardless of whether AcCoA is abundant gives a framework for manipulating cellular metabolism and signalling in many diseases.

These projects are related to 12266, and will allow us to compare the properties of the three enzymatically active pantothenate kinases.

This becomes interesting because these enzymes are expressed quite differentially, with Pank1 ('66) more present in the heart than the other two. These simulations will advance the state of research on this important protein, so that subsequent studies can better understand modulating compounds relevant to protecting damage to heart tissues during a heart attack by gliflozin molecules (such as Empagliflozin).

These two projects will help us understand what other effects such medication may have in other parts of the body beyond the heart.

pantothenate kinase 2

An enzyme that phosphorylates pantothenate to form phosphopantothenate.

Pantothenate kinase 2 is an enzyme crucial in the production of Acetyl-CoA, a vital molecule for cellular energy. It catalyzes the phosphorylation of pantothenate, converting it into phosphopantothenate, which is further processed into Acetyl-CoA.

Acetyl-CoA

A molecule that plays a central role in cellular metabolism.

Acetyl-CoA is a key molecule in cellular energy production. It's formed from pantothenate and serves as a precursor for various metabolic pathways, including the citric acid cycle, which generates ATP, the cell's primary energy source.

---

pantothenate

Vitamin B5, essential for the synthesis of Coenzyme A.

Pantothenate is a vital vitamin known as Vitamin B5. It's crucial for the production of Coenzyme A (CoA), a molecule involved in numerous metabolic reactions, particularly those related to energy production and fatty acid synthesis.

---

phosphopantothenate

An intermediate in the biosynthesis of Acetyl-CoA.

Phosphopantothenate is a molecule formed when pantothenate is phosphorylated by pantothenate kinase. It serves as a precursor to Acetyl-CoA, a key molecule involved in cellular energy production.

Pank1

Panthothenate kinase 1 gene.

Pank1 is the gene responsible for encoding pantothenate kinase 1. This enzyme plays a crucial role in synthesizing Acetyl-CoA, a vital molecule for cellular energy production.

Empagliflozin

A sodium-glucose cotransporter 2 (SGLT2) inhibitor used to treat type 2 diabetes.

Empagliflozin is a medication prescribed for type 2 diabetes. It works by inhibiting the SGLT2 transporter in the kidneys, preventing glucose reabsorption and increasing its excretion in urine.

---

gliflozin

A class of drugs that inhibit the sodium-glucose cotransporter 2 (SGLT2).

Gliflozin refers to a group of medications used to treat type 2 diabetes. They function by blocking the SGLT2 transporter in the kidneys, resulting in increased glucose excretion through urine.
