When two proteins' distance matrices share the same or similar features in approximately the same positions, they can be said to have similar folds with similar-length loops connecting their secondary structure elements.
Cando as matrices de distancia de dúas proteínas comparten as mesmas ou similares características en aproximadamente as mesmas posicións, pode dicirse que teñen similares pregamentos con bucles de lonxitude similar que conectan os seus elementos de estrutura secundaria.
