What is G-Actin (Globular Actin)?
G-Actin refers to the monomeric form of actin protein. It exists as individual globular units and serves as the building block for filament formation.
G-Actin Structure
The G-Actin structure has a globular shape and consists of a single polypeptide chain folded into a compact structure. It contains a binding site for ATP (adenosine triphosphate) and can bind to ATP or ADP (adenosine diphosphate).
- Solubility: G-Actin is soluble in aqueous solution allowing it to freely diffuse within the cell and interact with other proteins.
- Polymerization: When G-Actin molecules bind ATP and come together, they can polymerize to form F-Actin filaments.
Difference Between G-Actin and F-Actin
The difference between G-Actin and F-Actin lies in their structure and function. G-actin (globular actin) is a monomeric protein that polymerizes to form F-actin (filamentous actin), which is a long chain of actin monomers crucial for cell structure and movement. G-actin and F-actin are two forms of actin, a protein that plays critical roles in various cellular processes.
We will cover the difference between G-actin and F-actin in this article.
