... dramatically reduces the ability of mNBD1 to bind Hsc70. However, ATP can mediate this effect in two distinct ways. First, the binding and hydrolysis of ATP at the nucleotide- binding domain of Hsc70 ... its binding and release of substrates, reducing the affinity of their interaction. Once ADP occupies the nucleotide- binding site of Hsc70, it converts the...
