What is the structure of ATPase?

ATPase Structure The space between these two membranes is known as the intermediate space, while the space surrounded by the inner membrane is known as the matrix. The inner membrane also possesses numerous infoldings known as cristae, which contains the enzyme for ATP synthesis.

How many types of ATPase are there?

There are three classes of ATPases, which differ in structure and the type of ion that they transport; F-ATPases (e.g. mitochondrial H+-ATPase), P-ATPases (e.g. Ca2+-ATPase, Na+,K+-ATPase) and V-ATPases (e.g. lysosomal H+-ATPase).

What is ap type ATPase?

P-type ATPases use the energy from ATP hydrolysis to pump ions across the cell membrane against a concentration gradient. They form a large family of ubiquitous membrane proteins, and carry out many essential processes, such as generating the membrane potential or removing toxic ions from cells.

What is the function of p-type ATPase?

P-type ATPases are a large family of membrane proteins that perform active ion transport across biological membranes. In these proteins the energy-providing ATP hydrolysis is coupled to ion-transport that builds up or maintains the electrochemical potential gradients of one or two ion species across the membrane.

How does the Na +/ K+ ATPase maintain the membrane potential?

[3][4] The Na+K+-ATPase pump helps to maintain osmotic equilibrium and membrane potential in cells. The sodium and potassium move against the concentration gradients. The Na+ K+-ATPase pump maintains the gradient of a higher concentration of sodium extracellularly and a higher level of potassium intracellularly.

What is P-type semiconductor?

What is a p-type Semiconductor? A p-type semiconductor is an intrinsic semiconductor doped with boron (B) or indium (In). Silicon of Group IV has four valence electrons and boron of Group III has three valence electrons.

What is the example of V ATPase?

V-ATPases are also found in the plasma membranes of a wide variety of cells such as intercalated cells of the kidney, osteoclasts (bone resorbing cells), macrophages, neutrophils, sperm, midgut cells of insects, and certain tumor cells.

What are p class pumps?

The pumps belongs with this class is made up of two large identical catalytic α subunits, each carrying an ATP binding site, one of them get phosphorylated at aspartate residue during transport so they nominated as “P” class. They also contain two smaller β subunits concerned with regulatory functions.

How are the different types of ATPases different?

There are different types of ATPases, which can differ in function (ATP synthesis and/or hydrolysis), structure (F-, V- and A-ATPases contain rotary motors) and in the type of ions they transport.

What is the function of the vacuolar-type ATPase?

Vacuolar-type ATPase ( V-ATPase) is a highly conserved evolutionarily ancient enzyme with remarkably diverse functions in eukaryotic organisms. V-ATPases acidify a wide array of intracellular organelles and pump protons across the plasma membranes of numerous cell types.

Is the beta sheet of an ATPase found in nature?

Importantly, while all natural ATPases have some beta-sheet structure, the designed “Alternative ATPase” lacks beta sheet structure, demonstrating that this life-essential function is possible with sequences and structures not found in nature.

Where are F ATPases found in the mitochondria?

F-ATPases (F1FO-ATPases) in mitochondria, chloroplasts and bacterial plasma membranes are the prime producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). V-ATPases (V1VO-ATPases) are primarily found in eukaryotic vacuoles,…
