1gpb Summary



The structure was published by Acharya, K.R., Stuart, D.I., Varvill, K.M., and Johnson, L.N., in 1991 in a paper entitled "Glycogen Phosphorylase B: Description of the Protein Structure" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1990.

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

The PDB entry contains the structure of GLYCOGEN PHOSPHORYLASE B. This molecule has the UniProt identifier P00489 (PYGM_RABIT)search. The sample contained 842 residues which is 100% of the natural sequence. Out of 842 residues 822 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.
