We have isolated ribulose-1,5-bisphosphate-carboxylase/oxygenase (RUBISCO) from the red algae Galdieria Sulphuraria. The protein crystallized in two different crystal forms, the I422 crystal form being obtained from high salt and the P21 crystal form being obtained from lower concentration of salt and PEG. We report here the crystallization, preliminary stages of structure determination and the...
The crystallization and structural characterization of bovine liver catalase (BLC) has been intensively studied for decades. Forms I and II of BLC have previously been fully characterized using single-crystal X-ray diffraction. Form III has previously been analyzed by electron microscopy, but owing to the thinness of this crystal form an X-ray crystal structure had not been determined. Here, th...
Design of some crystal and quasicrystal networks, based on rhombellane tiling,is presented. [1,1,1]Propellane,is a synthesized organic molecule; its hydrogenated form, the bicyclo[1.1.1]pentane,may be represented by the complete bipartite graph K2,3 which is the smallest rhombellane. Topology of translational and radial structures involving rhombellanes is described in terms of vertex symbol, c...
Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determine...
