Indian Journal of Biochemistry & Biophysics. 2001 Feb-Apr; 38(1-2): 75-7http://imsear.searo.who.int/handle/123456789/27401Based on the experimental data and homologous sites in Protein Data Bank (PDB) a model for metal binding sites in D1/D2 heterodimer has been proposed. On searching for tetranuclear and binuclear Mn binding sites in the PDB, a suitable sequence homology in thermolysin and D1 could be observed. From the homology and site-directed mutagenesis data, a model for binuclear Mn-Ca or Mn-Mn has been built and it is extended to a tetranuclear Mn centre.engAlgae --chemistryAmino Acid SequenceBinding SitesCalcium --chemistryDatabases, FactualLigandsManganese --chemistryModels, MolecularMolecular Sequence DataMutagenesis, Site-DirectedPhotosynthetic Reaction Center Complex ProteinsProtein BindingSequence Homology, Amino AcidJournal Article
