Levels of protein structure shown by the myoglobin molecule

1A6M oxymyoglobin
Hovering the mouse pointer over each of the links below will bring in extra information.
Amino acid colour codes: ASP, GLU, CYS, MET, LYS, ARG, SER, THR, PHE, TYR, ASN, GLN, GLY, LEU, VAL, ILE, ALA, TRP, HIS and PRO.

PRIMARY STRUCTURE

Initial view shows the single polypeptide chain as a smooth trace, coloured by residues (see list above)

QUATERNARY STRUCTURE

Unlike haemoglobin, myoglobin does not have a quaternary structure, as it consists of a single polypeptide chain.

FUNCTION: OXYGEN STORAGE WITHIN MUSCLE
