napus to different concentrations of cell-free extract
, containing three variants of microcystin (MC-LR, MC-RR and MC-YR) for ten days at concentrations between 24 and 3000 mg [L.
Researchers detected Amase activity in cell-free extracts
of Thermus thermophilus HB8.
14]C]citrulline into [Sigma]A + U by intact cells and on the activities of glutamine synthetase (GS) and carbamylphosphate synthetase (CPSase) in cell-free extracts
of YFE leaves from salinized and control plants of both species.
The Program is also devoted to the development and application of powerful new imaging tools that permit such studies directly in living cells and functional cell-free extracts
In crude extracts of yeast, the sterol 14[alpha]-demethylase is inhibited by flusilazole approximately 100 times more efficiently than in crude cell-free extracts
from rat liver (Trzaskos and Henry 1989).
However, whole cells and cell-free extracts
of lactococci do not produce the compound under simulated cheese conditions in the laboratory.
We inhibited the motor activity of myosin-II in cell-free extracts
of clam (Spisula solidissima) oocytes with a function-blocking myosin-II-specific antibody to investigate the mechanism of movement of myosin-II to the contractile ring.
