PROTEIN STRUCTURE
Cards in this deck (10)
- 1Bonds in Teritiary structure of proteinHydrophobic interactions
- 2ENTROPY (S) of solvent and protein during foldingS(solvent) increases
S(protein) decreases
Overall entropy increases during protein folding - 3where can be hydrophobic residues and hydrophilic residues found after protein folding?Hydrophilic residues - on the surface of globular protein
Hydrophobic residues - buried inside the hydrophobic core of globular protein - 4Quarternary structurearrangement of multiple polypeptide chains in 3-dimensional space
- 5Bonds involved in quarternary structureIntermolecular disulfide, intermolecular hydrophobic, intermolecular hydrogen and intermolecular salt bridges or ionic bonds
- 6hemoglobin structure* 2 alpha and 2 beta chain
* hydrogen bond responsible for the formation of quarternary structure not disulfide - 7Function of Hb and MbHb - transport oxygen as well as carbon dioxide
Mb - store oxygen inside the muscle cells - 8Homolog Analog Paralog OrthologHomolog- same gene but diff. function
Analog- diff gene but same function
Paralog- gene duplication event within the same organism
Ortholog- gene duplication event within two organism - 9Can 2 proteins with low sequence similarity have similar structure or fold?yes.
- 10How evolutionary relationship can be established between two protein?On the basis of their sequence not on the basis of structure
