Abstract excerpt
The homodimeric SecA protein is the peripheral subunit of the translocase, and couples the hydrolysis of ATP to the translocation of precursor proteins across the bacterial cytoplasmic membrane. The high affinity ATP binding activity of SecA resides in the amino-terminal domain of SecA. This domain contains a tandem repeat of the "so-called" Walker B-motif, hXhhD (Walker, J.E., Saraste, M., Runswick, M.J., and...
