==About this Structure==
</table>
[[2fsf]] is a 2 chain structure of [[SecA]] with sequence from [http://en.wikipedia.org/wiki/Escherichia_coli Escherichia coli]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=2FSF OCA].  
== Function ==
[https://www.uniprot.org/uniprot/SECA_ECOLI SECA_ECOLI] Required for protein export, interacts with the SecYEG preprotein conducting channel. SecA has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.<ref>PMID:15140892</ref>
