Crystal Structure of E. Coli RecA in a Compressed Helical Filament Form 2

The structure was published by Xing, X. and Bell, C.E., in 2004 in a paper entitled "Crystal structures of Escherichia coli RecA in a compressed helical filament." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2004.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of RecA protein. This molecule has the UniProt identifier P0A7G6 (RECA_ECOLI)search. The sample contained 356 residues which is 100% of the natural sequence. Out of 356 residues 306 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homohexamers.
