1s6i Summary


Ca2+-regulatory region (CLD) from soybean calcium-dependent protein kinase-alpha (CDPK) in the presence of Ca2+ and the junction domain (JD)

The structure was published by Weljie, A.M. and Vogel, H.J., in 2004 in a paper entitled "Unexpected structure of the Ca2+-regulatory region from soybean calcium-dependent protein kinase-alpha" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2004.

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

The PDB entry contains the structure of Calcium-dependent protein kinase SK5. This molecule has the UniProt identifier P28583 (CDPK_SOYBN)search. The sample contained 188 residues which is < 90% of the natural sequence. Out of 188 residues 182 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 is most likely monomeric.
