A structuring and eventual exclusion of water surrounding backbone hydrogen bonds takes place during protein fold-ing as hydrophobic residues cluster around such bonds. Taken as an average over all hydrogen bonds, the extent of desolvation is nearly a constant of motion, as revealed by re-examination of the longest all-atom trajectory with explicit solvent [Y.Duan & P.A.Kollman (1998)Science 282, 740].Furthermore, this extent of desolvation is pre-served across native soluble proteins, except for cellular prion proteins....

Chymotrypsin is a prominent member of the family of serine proteases. The present studies demonstrate the presence of a native fragment contain-ing 14 residues from Ile16 to Trp29 in a-chymotrypsin that binds to chy-motrypsin at the active site with an exceptionally high affinity of 2.7 ± 0.3·10 )11 mand thus works as a highly potent competitive inhib-itor. The commercially available a-chymotrypsin was processed through a three phase partitioning system (TPP). The treated enzyme showed consid-erably enhanced activity. ...

An exception is any error condition or unexpected behavior encountered by an executing program. Exceptions can be raised because of a fault in your code or in code you call (such as a shared library), unavailable operating system resources, unexpected conditions the common language runtime encounters (such as code that cannot be verified), and so on.

Catalytic oxidation of organic compounds is an extremely important field of chemistry, spanning the range from biological oxidations to large scale industrial production of commodity chemicals. However, many of these transformations can hardly be classified as organometallic reactions, since the catalysts (often simple metal salts) and the intermediates can be rather regarded as coordination complexes than organometallic compounds.

Ethernet-based data services offer the opportunity to create differentiation, command premium pricing, and earn higher margin for such value-added data services as transparent LANs, storage area networks, and virtual private networks. Extending native 10/100Base-T and Gigabit Ethernet services across the LAN, WAN, and MAN means data services are less expensive to deploy, provision quickly, and offer exceptional reliability and security.
