Secondary structure features that involve residues that are contiguous in sequence appear on the matrix's main diagonal; other diagonals in the matrix reflect spatial contacts between residues that are not near each other in the sequence.
As peculiaridades da estrutura secundaria que implican residuos contiguos na secuencia aparecen na diagonal principal da matriz; outras diagonais na matriz reflicten contactos espaciais entre residuos que non están próximos un ao outro na secuencia.
