The phrase "amount of snare" is correct and usable in written English.
It can be used when discussing the quantity or level of a snare, often in contexts related to music, sound, or traps.
Example: "The amount of snare in this track gives it a lively and energetic feel."
Alternatives: "level of snare" or "quantity of snare".
First, we measured SNARE complexes in drug-treated rats in basal conditions (without stress); we found that in P/FC chronic antidepressant treatments did not induce significant changes in the amount of SNARE complexes (Fig. S2), in line with the lack of changes in depolarization-evoked glutamate release (see Fig. 2A D).
Löfke et al.'s findings suggest that auxin restricts the growth of root epidermal cells by controlling the amount of SNARE proteins in the vacuole membrane.
Even a parsimonious model typically has several free parameters, such as, in this case, binding affinities or total amounts of SNAREs or coats.
5) The authors argue that trans-SNARE complexes alone are not sufficient for fusion because some trans SNARE complexes were formed in the absence of HOPS and HOPS increases the amount of trans SNARE complexes three-fold while stimulating fusion 100-fold.
To estimate the amount of trans-SNARE association that formed during a reaction, the amount of Nyv1p that co-immunoprecipitated with Vam3p was determined.
Adding HOPS increases the amount of trans-SNARE interaction only a few fold, while it increases the rate of fusion much more dramatically (> 100-fold).
The addition of HOPS stimulates the fusion reaction more than 100-fold, yet it only increases the amount of trans-SNARE interaction a few-fold.
Since the amount of trans-SNARE interaction that was detected at low Nyv1p levels with HOPS was lower than the amount seen with high Nyv1p levels without HOPS, yet the amount of fusion was drastically higher in the sample containing HOPS, the requirement for high cooperativity can be ruled out as an explanation for the observed discrepancy between increases in trans-SNARE interaction and fusion.
Thus tethering has a role in promoting membrane fusion that extends beyond simply increasing the amount of total trans-SNARE complex.
Lower levels of Nyv1p did not lead to a drastic diminution of fusion activity, but resulted in lower amounts of trans-SNARE association.
Zick and Wickner found that the HOPS complex does not enable fusion by just increasing the amount of interactions between the SNARE proteins.
