Crystal structure of obelin following Ca2+ triggered bioluminescence suggests neutral coelenteramide as the primary excited state
The structure was published by Liu, Z.J., Stepanyuk, G.A., Vysotski, E.S., et al., Markova, S.V., Malikova, N.P., and Wang, B.C., in 2006 in a paper entitled "Crystal structure of obelin after Ca2+-triggered bioluminescence suggests neutral coelenteramide as the primary excited state." (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 1.93 Å and deposited in 2005.
The experimental data on which the structure is based was also deposited.
The PDB entry contains the structure of Obelin. This molecule has the UniProt identifier Q27709 (OBL_OBELO). The sample contained 195 residues which is 100% of the natural sequence. Out of 195 residues 190 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.
