Fold distribution of different backbone conformations of disulphide bonds: Alpha, beta, alpha/beta, alpha+beta, and small proteins are different SCOP fold classes; C/E/H are coil/strand/helical conformations of the half-cystines. a) Backbone conformational preferences of disulphide bonds in different fold classes, b) Distribution of disulphide bond backbone conformations into different conservation classes; L-low or poorly conserved, M-medium conserved, and H-highly conserved.
