Cylinders and barrels. The twisted P sheets of proteins are often curved to form structures known as P cylinders or p barrels (Fig. 2-16).113 114 Simple cylinders formed by parallel P strands form the backbones of the electron transport protein plastocyanin, the enzyme superoxide dismutase, the oxygen carrier... 

Figure 12 2-D in-phase-antiphase spectrum correlating backbone C and N nuclei, with detection of C (CON-in-phase-antiphase (CON-IPAP) experiment). Data were acquired on a 1.5 mM sample of C, N labeled reduced monomeric superoxide dismutase with a 14.1 T Bruker Avance spectrometer equipped with a cryogenically cooled probehead optimized for C detection at 298 K.

Fig. 2.50. Comparison of step-by-step build-up of backbone configurations for superoxide dismutase (down the left side) and an immunoglobulin variable domain (down the right side). New backbone added at each step is shown by heavy arrows (from Richardson et al., 1976).
