1nxt Summary


MicArec pH 4.0

The structure was published by Bent, C.J., Isaacs, N.W., Mitchell, T.J., and Riboldi-Tunnicliffe, A., in 2004 in a paper entitled "Crystal structure of the response regulator 02 receiver domain, the essential YycF two-component system of Streptococcus pneumoniae in both complexed and native states." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.34 Å and deposited in 2003.

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

The PDB entry contains the structure of DNA-binding response regulator. This molecule has the UniProt identifier Q9S1K0 (Q9S1K0_STREE)search. The sample contained 120 residues which is < 90% of the natural sequence. Out of 120 residues 116 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 homodimers.
