The phrase "a functional importance" is correct and usable in written English.
It can be used when discussing the significance or role of something in a practical or operational context.
Example: "In this study, we will explore the functional importance of biodiversity in maintaining ecosystem health."
Alternatives: "a practical significance" or "an operational relevance".
The fundamental role of the octanoyl chain on Ser3 and the aromatic group of Phe4 in membrane-binding strikingly resembles the importance of these two residues for ghrelin function, suggesting a functional importance of ghrelin binding to membranes.
This glutamic acid residue and its surrounding sequence have been conserved during eukaryotic evolution, suggesting a functional importance.
On the other hand, some data indirectly show that a certain region of loop III is likely to have a functional importance.
Changes in the chimeric leader occurring several times independently and changes that are fixed in subsequent generations therefore most likely have a functional importance.
As these observations point to a functional importance of BicD phosphorylation, we set out to study the molecular basis of this phenotype.
A functional importance for the physical protein interactions was evidenced by the abilities of RECQ1 to stimulate the endo- and exo-nucleolytic incision activities of EXO-1 and MSH2-MSH6 to enhance RECQ1 helicase activity [13].
The position of the turns appears to be evolutionary conserved among different species, as shown by a multiple sequence alignment of seven vertebrate shrew-1 homologues, suggesting a fundamental functional importance of this region (Suppl. Figure S1).
Correlation analyses identified an E1-I2 length-correlation in Group O and Group J and an N-E3 length-correlation in Group J. Taken together, these results suggest a possible functional importance of LT length in the GPCR superfamily.
The relatively reduced selection constraints of STSP members are consistent with a lesser functional importance and suggest that many are progressing toward becoming pseudogenes.
Several studies have hinted at a disproportionate functional importance of U34 modifications in these three isoacceptors.
Consequently, there may be a greater functional importance on molecular 3D conformation over the primary sequence.
