The phrase "a structural role of" is correct and usable in written English.
It can be used when discussing the function or importance of a particular element within a system or framework.
Example: "The committee plays a structural role of ensuring that all voices are heard in the decision-making process."
Alternatives: "a foundational role of" or "a key function of".
Interestingly, the phenylalanine-mutants, designed as negative controls were the most active mutants which suggests rather a structural role of His106.
Our work thus potentially highlights a structural role of Thr59 and Ser65 in the formation of critical intramolecular interactions for ligand binding and signal transduction of D1-class dopaminergic receptors.
Therefore, the absence of interaction of the W173G recombinant protein and the reduced interactions of the Y95G and I154F recombinant proteins most likely reflect a structural role of these residues (Fig 3A).
Alternatively, also a structural role of SNAREs has been envisioned (Di Sansebastiano, 2013), which could be yet another mechanism to impact on vacuolar organisation.
Also, ceramides have been found in the membrane of the autophagosome, in line with the idea of a structural role of sphingolipids in autophagy [ 131].
There is a structural role of lamins in assembly and maintenance of the nuclear envelope, nuclear shape, and anchoring of nuclear pore complexes (Hutchison, 2002; Dechat et al., 2008).
The exact mechanisms of action of Si on bone are still unclear, and both a metabolic role (a co-factor for prolyl hydroxylase) and a structural role (stabilisation of collagen) have been proposed [2,13,25].
It is of interest that the same epitope was also found in guard cells of Psilotum [ 56], suggesting that they might fulfil a structural role in stomata of early tracheophytes.
They have a structural role, and the structures of individual connective-tissue polysaccharides are related to specific animal functions; hyaluronic acid, for example, the major component of joint fluid in animals, functions as a lubricating agent and shock absorber.
Therefore, at this stage of the biofilm maturation, extracellular DNA does not appear to play a structural role in biofilms of these three Sulfolobus strains.
In addition to a structural role, the subtelomeres of human chromosomes contain many gene families, mostly originated from duplication events [ 13, 14].
