Sentence examples for constriction system from inspiring English sources

The most common membrane constriction system in prokaryotes is based on the tubulin homologue FtsZ, whose filaments in E. coli are anchored to the membrane by FtsA and enable the formation of the Z-ring and divisome.

Here, we show that envelope machines facilitating septal PG synthesis (PBP1B-LpoB complex) and OM constriction (Tol system) are physically and functionally coordinated via YbgF, renamed CpoB (Coordinator of PG synthesis and OM constriction, associated with PBP1 B).

A simple piston-constriction-pipe system is analyzed as a first step in the modelling of a "one cylinder cold engine".

Furthermore, we reconstituted a minimal constriction force-generating system from purified components in vitro, encapsulating Thermotoga maritima FtsA (TmFtsA) and FtsZ (TmFtsZ) in liposomes of sizes corresponding to those of a bacterial cell.

A second study in Drosophila examined the effects of Pygo mutation on cuticle patterning, midgut constriction, central nervous system, and cardiac development, and concluded that " Pygo is an essential component in the Wg signal transduction pathway".

Constrictions in the system are essential to the building up of pressure before an eruption.

To avoid the production of mini cells due to polar constrictions, the Min system inhibits FtsZ polymerization near the cell poles (2, 8), and the nucleoid occlusion (Noc) protein SlmA, which is associated with the bacterial chromosome, inhibits FtsZ polymerization in the vicinity of the nucleoid (9).

A major function of their contractility appears to be to decrease the capacity of the cardiovascular system by constriction of the peripheral vessels in response to the heart's inability to pump sufficient blood.

In order to elucidate possible mechanism, the acetic acid induced writhing test is deficient in specificity; as different mechanism may be implicated in the reduction of muscular constriction for instance, sympathetic system through the release of biogenic amines, cyclooxygenases and their metabolites inhibition and through opioids receptors mechanisms [ 18].

From a mechanistic point of view, the lack of specificity in acetic acid-induced writhing test suggests the involvement of different nociceptive mechanisms in the reduction of muscular constriction, such as sympathetic system, through the release of biogenic amines, cyclooxygenases and their metabolites inhibition, and through opioids receptors mechanisms [ 43].

If that happens, Lyon writes, we're stuck with a slow, closed system whose constrictions prevent genetic information from helping even those who provide it.
