Common ‘world’ coordinate

Each of the carefully designed molecules is duly transformed into a common world coordinate system, which eventually permits the individual molecules to be positioned strategically with respect to one another. 

As OPEC s share of the world oil supply market continued to fall in the 1990s, they began taking steps to better coordinate production with iron-OPEC producers such as Mexico and other members of the Independent Petroleum Exporting Countries (IPEC). By exchanging information, and undertaking joint studies of issues of common interest, the hope was to stabilize prices and improve the economic outlook for all oil producers. This collaboration between OPEC and major non-OPEC producers helped raise oil prices to over 27 a barrel in 1999 from a low of less than 13 in 1998. 

Then later in an aerobic world with mainly iron(III) both, zinc peptidases and iron oxygenases, evolved from these ancestors. Today nature mainly uses zinc centers in metalloenzymes for the hydrolyses of peptide bonds (99,J00). In the commonly accepted mechanism for zinc peptidases, zinc(II) has two tasks It polarizes the carbonyl functionality of the peptide bond that is going to be cleaved and it supports the deprotonation of the coordinated water nucleophile. 

The Protein Data Bank (PDB) at Brookhaven National Laboratory is a database containing experimentally determined, three-dimensional structures of proteins, nucleic acids, and other biological macromolecules. The PDB has a history of service starting in 1971 to a global community of researchers, educators, and students in a variety of scientific disciplines. The archives contain atomic coordinates, bibliographic citations, primary and secondary structure information, as well as crystallographic structure factors and NMR experimental data. Scientists around the world contribute structures to the PDB and use it on a daily basis. The common interest shared by this community is a need to access information that can relate the biological functions of macromolecules to their three-dimensional structures. 

K and appears to be bluish white. The CIE Standard Illuminant D65 (Figure 12.2b) is a commonly used standard illuminant that tries to portray standard illumination conditions in the open air in different parts of the world. It represents average daylight and has a CCT of approximately 6500 K (exactly 6504 K). The CIE 1931 color space chromaticity coordinates of D65 are x = 0.3128,3 = 0.3290, which is close to a white-point in the CIE diagram.
