The crystal structure of cpFtsY from Arabidopsis thaliana
OverviewOverview
Two GTPases in the signal recognition particle and its receptor (FtsY) regulate protein targeting to the membrane by formation of a heterodimeric complex. The activation of both GTPases in the complex is essential for protein translocation. We present the crystal structure of chloroplast FtsY (cpFtsY) at 1.75 A resolution. The comparison with FtsY structures in different nucleotide bound states shows structural changes relevant for GTPase activation and provides insights in how cpFtsY is pre-organized for complex formation with cpSRP54. The structure contains an amino-terminal amphipathic helix similar to the membrane targeting sequence of Escherichia coli FtsY. In cpFtsY this motif is extended, which might be responsible for the enhanced attachment of the protein to the thylakoid membrane.
