The ATPase domain is essential during the interactions of the proteins Hsp70 and subunit Tim44. Without the presence of ATPase, carboxy-terminal segment is not able to bind to protein of Tim44. As mtHsp70 transmits the nucleotide state of the ATPase domain with alpha-helices A and B, Tim44 interacts
