MSH2-MSH6 é responsável por iniciar reparação de erros de replicação de DNA. Aqui nós apresentamos uma abordagem cinética transitória para a compreensão crítica como esta proteína funciona. O relatório ilustra stopped-flow experimentos para medir a ligação DNA acopladas e cinética ATPase subjacente MSH2-MSH6 mecanismo de ação no reparo do DNA.
