3cg8 Summary


Laccase from Streptomyces coelicolor

The structure was published by Skalova, T., Dohnalek, J., Ostergaard, L.H., et al., Duskova, J., Stepankova, A., and Hasek, J., in 2009 in a paper entitled "The Structure of the Small Laccase from Streptomyces coelicolor Reveals a Link between Laccases and Nitrite Reductases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.679 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of laccase.

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 homotrimers.
