4k99 Summary


Structure of Ternary Complex of cGAS with dsDNA and Bound 5 -pppdG(2 ,5 )pdG

The structure was published by Gao, P., Ascano, M., Wu, Y., et al., Hartmann, G., Tuschl, T., and Patel, D.J., in 2013 in a paper entitled "Cyclic [G(2',5')pA(3',5')p] is the metazoan second messenger produced by DNA-activated cyclic GMP-AMP synthase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 2013.

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

This PDB entry contains a complex of 3 biomacromolecules, namely Cyclic GMP-AMP synthase, DNA-F, and DNA-R.

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 heterotrimers.
