SECA_MOTOR_DEAD(IPR014018)depends on its subcellular location. The secA proteins of eubacteria are essential for protein export. The proteins secY and secE, which are part of the protein translocation system, interact with it. It's crucial for linking ATP hydrolysis with protein translocation across membranes. SecA is a helicase in superfamily 2 (SF2), which is a class of helicases that can translocate proteins. It has the signature seven SF2 motifs found in the core of dead or glucose ATPases. During the ATPase cycle, the two recA-like domains of the helicase move in relation to each other. This movement of the domains moves the helicase along the nucleic acid.
