Domains are either:
- alpha - 4-helix (Rop protein in plasmids); globin fold
- beta - antiparallel; (enzymes, transport porteins, antibodies); immunoglobin fold, b-barrel
- alpha/beta - the most common, found in all types of proteins Rossman fold; a/b barrel
There are many variants of these three general categories...
e.g. the GLOBIN fold, 8 helicies (A-H)
an a-domain: single domain protein
Sperm whale myoglibin (heamoglobin similar with 4 subunits)
