Glyceraldehyde-3-phosphate dehydrogenase
Introduction and Basic Structure
|
Glyceraldehyde-3-phosphate dehydrogenase, or more commonly called, , is a tetrahedral protein. G-3-P is an enzyme used in glycolysis to produce NADH through a mechanism with phosphate and NAD+, which binds to the ligand binding site of G-3-P. The G-3-P is converted to 3-phospho-D-glyceroyl-phosphate. The has both alpha helices (purple) and beta sheets (green). The alpha helices are in four separate sections, but are mostly on the external sections of the enzyme. The beta sheets are closer to the center of the enzyme. The shows a more accurate representation of what this enzyme looks like.
Bonding
The are colored in orange. Based on the amount of the thin orange lines, it is clear that there are many hydrogen bonds. However, there are no within the structure, or they would have been highlighted in green. The only special binding in the G-3-P enzyme is the hydrogen bonding. Looking at the structure with the highlights the structure of the beta sheets. The image shows that majority of the beta sheets are parallel in structure, but there are a few anti-parallel sections of the beta sheets.
Residues
The are shown in grey. The are shown in royal blue. The hydrophobic residues are on the internal part of the enzyme while the hydrophilic sections surround the hydrophobic residues.
