The phrase "a distinct subclass of" is correct and usable in written English.
It can be used when categorizing or specifying a particular group within a broader classification.
Example: "Mammals are a distinct subclass of vertebrates, characterized by their ability to nurse their young."
Alternatives: "a unique category of" or "a specific type of".
As is the case with H4R3me2s, it is not clear whether the different distribution of the H4R3me2a modification represents different stages of differentiation and commitment of the OLPs or just marks a distinct subclass of these precursors.
Lévi (1973) later proposed to classify them as a distinct subclass of the Demospongiae [21], a rank maintained in the most authoritative recent classification "Systema Porifera: a guide to the classification of sponges" [22].
Consistent with this hypothesis, stable phase differences among SCN neurons within organotypic slices are disrupted when intercellular communication is inhibited [3], and the capacity to oscillate in the absence of intercellular communication does not correspond to a distinct subclass of SCN neurons [40].
More precisely, each row represents a distinct subclass of the class Transmission pattern, which is a subclass of biotop: BiologicalProcess.
However, an alternative interpretation is that BDNF induces the formation of a distinct subclass of integrin adhesions in the growth cone that are α-actinin negative.
However, sporadic reports in which significant therapeutic potential was achieved [ 4- 6] suggest that a distinct subclass of patients with an infectious-associated phenotype may exist.
DPSL proteins are a phylogenetically distinct subclass of di-iron carboxylate proteins that assemble into a homo-dodecameric cage ∼10 nm in diameter and are widely distributed in phylogenetically diverse prokaryotes [9], [31].
The SIBLING family has recently been suggested to be included as a distinct subclass (called the "acidic" gene cluster) of a larger cluster of genes, the secretory calcium-binding phosphoprotein (SCPP) [ 2].
This led to identification of the so-called 'triple negative' class (tumours negative with respect to expression of ER and progesterone receptor that, in addition, lack over-expression and/or amplification of HER2) as a distinct subclass.
This group of proteins thus shared primary structure determinants which defined a distinct subclass in the protein family.
However, ∼12% of CRC samples are non- APC mutated and represent a distinct subclass characterized by a serrated histopathology, the V600E BRAF mutation and the CpG island methylator-high phenotype (CIMP-H).
