Oxalate is commonly present in higher plants and often accumulated at substantial concentrations in the plant biomass, the calcium salt of which can function as antiherbivore defensive agent (Franceschi and Nakata 2005).
Whilst this condition may hold in a few in vitro conditions, such as uptake into oocytes, or exit fluxes from cells or vesicles into large volume of bathing solution, it is unattainable with net intestinal transport, where the cytosolic and interstitial fluids contain transported ligands at substantial concentrations.
Our previous studies had shown that in the dga1Δlro1Δare1Δare2Δhem1Δ (QM hem1Δ) mutant which is unable to produce TG and SE and does not contain LP, squalene formed at large amounts due to the deletion of HEM1 is stored in the ER and plasma membrane at substantial concentrations [13].
From its amino acid profile, all essential amino acids such as lysine, methionine, threonine, tryptophan, histidine, leucine, isoleucine, valine and phenylalanine were present in the protein concentrate at substantial concentration (Smith and Nielsen 2010).
The study also confirmed that, as an enzyme complex, in order for cellulase to be efficient, the presence of all the components at substantial concentration is highly required and that the presence of β-glucosidase at a high concentration would not help in case FPase is not present at high enough concentration to initiate the cellulolytic reaction.
As shown in Fig. 4(A) and (B), ICI 118,551 (at a substantial concentration of 100 nM) did not inhibit the ability of isoprenaline to activate ICl.PKA, nor was the ability of Ni2+ to inhibit isoprenaline-activated current impaired.
Therefore, the results of this study are in accordance with those reported in other research [ 3, 27] that laid emphasis on the need for the presence of FPase at a substantial concentration in the cellulase enzyme complex for an efficient hydrolysis.
It should be pointed out that the inhibitory effect of HIV PIs in vitro were observed at substantial PI concentrations (µM range), much higher than those needed for HIV peptidase inhibition (on the nM order) [33].
Minimal pH value was 4.4 in the diffuse flow, and substantial concentrations of dissolved ferrous iron were present at this site (up to 42 µM among the tubeworms).
"I'm sure the Justice Department and the F.T.C. will look closely at the pretty substantial concentration of market power these companies will have in the energy-trading area".
As argued above, at small drug doses, substantial concentration of sIL-6Rα remains in circulation and any IL-6/sIL-6Rα complex blocked by the antibody is quickly replenished, negating the effect of targeting the complex.
