The phrase 'constitute a minor proportion' is correct and can be used in written English.
You can use this phrase when referring to a small portion of something that is a part of a whole. For example, "The number of customers who received poor service constituted a minor proportion of those surveyed."
Manufactured goods constitute a minor proportion of Oklahoma's economy, as compared to the production of raw materials.
In humans, γδ T cells constitute a minor proportion of T cells that are thought to be involved in tumour surveillance.
Finally, the incidences of tumours in all the major morphological subgroups increased, as did that of tumours that were not histologically verified, although they continued to constitute a minor proportion of CNS tumours.
This contrasts with our ChIP-seq data, where promoter and 5' gene region binding of FUS only constitutes a minor proportion of the FUS in situ targets.
INS-GFP+ cells producing neither hormone constituted a minor proportion of the population; however, it is possible that these cells produced other hormones that were not assayed (e.g. pancreatic polypeptide [PPY], ghrelin [GHRL]).
This may be explained by the fact that our hospital is geographically located in a rural area and that over 90% of the microbiological specimens received in our laboratory originates either from hospitalized patients or from patients regularly visiting the polyclinics; thus the group of patients with true community acquired infections clearly constitutes a minor proportion in our setting.
NK cells constitute only a minor proportion of the infiltrate.
From a technical perspective, species identification based on the whole-genome sequencing should also be feasible since the large, non-protein-coding part of eucaryotic genomes evolves rather quickly and strongly conserved gene exons constitute only a minor proportion, e.g. roughly 1.5% of a mammalian genome [ 22].
This has been already shown by the comparison of the DeepCAGE data with in situ hybridization for the hippocampus [ 30] and reported for ORs in the gut, where they were expressed exclusively in gastrointestinal enterochromaffin cells, which constitute only a minor proportion of the total intestinal epithelium [ 31].
Thus, H3K4/K27me3 promoters constitute a minor yet significant proportion of promoters in both lineages.
