1. Describing a security that is traded with relative frequency. Many investors look to active securities because they can be traded, even in rather large quantities, without affecting the price. Active securities usually have a low bid-ask spread.

2. Describing a market or exchange with a high trading volume.

The common approach mentioned above could not analyze the nature of the local active sites or the structuring surface providing only the average reaction rate.
This unusual result can be explained by the formation of bimolecular species between propagating chains and the neodymium complex, which causes the decrease of the number of active sites and consequently of the polymer yield.
Lib dock docks ligand into the active site by calculating hot spots and using polar and a polar probes and these hot spots are further used to align ligands to form interactions 16.
Upon binding of the substrate/product to the active site, large (~20[degrees]) rotation of the large domain is induced with respect to the small and clasp domains [6-9].
[beta] Cas are also zinc metalloenzymes; however the zinc is coordinated by two Cys and one His in the active site (x, x+56, x+59, where x=68 in Can2) [38].
Molecular dynamics simulations provided an insight into the role of molecules of water in the enzyme active site. ANF forms the hydrogen bond with a water molecule, but during the simulations, different water molecules interact with ANF at different points of time [70].
As for AutoDock, the grid map consisted of 80 [Angstrom] x 80 [Angstrom] x 80 [Angstrom] points around the active site, with a grid spacing of 0.375 [Angstrom].
There are enough spaces in the active site pocket to accommodate extended groups at the two ends of the CAN scaffold.
Here, we present a reliable bioinformatics classroom module into an introductory biochemistry course, which identifies two critical aspects of hands-on activity: building phylogeny and 3D structure of the active site of the target enzyme, [alpha]-amylase.
Polar hydrogens were added to each receptor; the grid was located in the pocket of the active site for each model.
However, in the past two months, staff at the King County Department of Permitting and Environmental Review (DPER) received noise complaints from the more than 50 homes within a quarter-mile of the active site. "It's just in the last month that they've produced enough product to have trucks come in," Fred White, a DPER inspector overseeing the quarry site told the Snoqualmie Valley Record.
