PHOSPHATE SYSTEM POSITIVE REGULATORY PROTEIN PHO4/DNA COMPLEX

The structure was published by Shimizu, T., Toumoto, A., Ihara, K., et al., Ogawa, N., Oshima, Y., and Hakoshima, T., in 1997 in a paper entitled "Crystal structure of PHO4 bHLH domain-DNA complex: flanking base recognition." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely DNA (5'-D(*CP*TP*CP*AP*CP*AP*CP*GP*TP*GP*GP*GP*AP*CP*TP*AP*G )-3'), DNA (5'-D(*CP*TP*AP*GP*TP*CP*CP*CP*AP*CP*GP*TP*GP*TP*GP*AP*G )-3'), and PROTEIN (PHOSPHATE SYSTEM POSITIVE REGULATORY PROTEIN PHO4).

The molecule most likely forms heterotetramers.
