- Keratin
- π-π stacking interactions
- Ubiquitin, Proteasomes
- Chemical polarity of amino acids: FAMILYVW - hydrophobic, DEHKNQRST - polar, GPC - special
- Proline (Pro, P) is special:
- It's a secondary amino acid (AKA imino acids, although this nomenclature is disputed)
- It's conformationally locked (backbone dihedral angle φ fixed to about −75°) → very rigid, loses less conformational entropy upon folding, found in turns
- Protein structure:
- Primary structure: sequence of amino acid backbone (plus cross-linking such as disulfide bonds)
- Secondary structure: alpha helices, beta strands (plus rare others)
- Tertiary structure: three-dimensional structure (full set of atomic coordinates in 3D space) - determined by protein crystallography or protein NMR
- Quaternary structure: arrangement of multiple folded protein molecules in a multi-subunit complex - XRD again
- Ramachandran plot
- UV-Vis spectroscopy can be used to determine protein concentration - aromatic amino acid side chains (K, Y, W, H) absorb UV
- Supersecondary structure:
- Plastocyanins - Cu redox centre converts between Cu(I) and Cu(II), coordination geometry of Cu is not optimal for either oxidation state, making neither favoured and thus interconversion facile. Structures: PDB 3BQV, PDB 1PNC.
-

-
Residues coordinating Cu in plastocyanin
-
Cu coordination geometry
- EF hand - chiral, right-handed enantiomer only (with one exception). Aspartic acid residues bind Ca2+ (important in calcium signaling) in loop between two alpha helices.
- Beta hairpin - major structural unit, two beta strands antiparallel
- βαβ motif - two beta strands parallel, chiral (alpha helix either above or below plane of beta strands), only right-handed enantiomer found in nature
- Coiled coil - HPPHPPP repeat gives 3.5 not 3.6 residues per turn, so hydrophobic seam slowly curves - myosin, keratin
- Polyproline helix?
- Collagen helix?
- Tertiary structure:
- all α-structures (αα) - buffers, triggers, allostery
- calbindin - (2 × EF hand) mops up loose Ca2+
- myosin - baby brother of haemoglobin - 8 helices, haem group binds Fe and thus O2
- all β-structures (ββ) - hard-as-nails brick walls → rigidity
- viral capsids
- plastocyanin
- antibodies
- all α-structures (αα) - buffers, triggers, allostery
