Figure 2From: Graph-representation of oxidative folding pathwaysNomenclature for disulfide topologies. Disulfides can be labeled by the sequence positions, or simply by the sequential number of the cysteine residues they connect (1–3, 2–4 topology). Alternatively, it is customary to alphabetically label the disulfide bridges, and and to assign bridge label to the cysteines, starting from the N terminus (abab topology).Back to article page
