The phrase "as a separate subunit" is correct and usable in written English.
It can be used in contexts where you want to specify that something is functioning or being considered independently within a larger system or structure.
Example: "The research team decided to analyze the data as a separate subunit to ensure more accurate results."
Alternatives: "as an independent component" or "as a distinct unit".
Therefore, it is identified as a separate subunit (1A).
Thus we find the 5.8S rRNA, either cleaved as a separate subunit, or fused to the large rRNA subunit (no ITS2 present).
Even when this occurs, extension beyond this mismatched nucleotide is seldom observed, and the mismatched nucleotide residue is nearly always removed by an exonuclease activity that may be present either in a separate domain of the pol or as a separate subunit of the replicase.
At the next step, we identified and removed from further analysis 106 EC nodes that were represented by two or more sequence clusters but each cluster corresponded to a separate subunit of a heteromeric multi-subunit enzyme, as judged by UniProt, COG and/or CDD annotations of representatives of these clusters.
Canonical E1 enzymes contain two Rossmann-type folds (either as domains within the same polypeptide chain or as separate subunits in the context of a heterodimer), a domain containing the catalytic cysteine (the cysteine domain), and a ubiquitin-fold domain [ 31, 37, 38] (for review, see [ 39]).
It has been reported as a complex of three proteins (98, 88 and 76 kDa) but retains some biological activity as separate subunits [ 37, 38].
The β and γ subunits can occur as gene fusions in plants [32] or the β subunit can occur as a separate protein that interacts with the catalytic α-subunit in transient assays [33].
A separate A subunit was found, but no other G subunit is present.
Instead, it appears that, like nad1 (Seilhamer, Gutell, et al. 1984; Seilhamer, Olsen, et al. 1984; Heinonen et al. 1987; Pritchard et al. 1990; Schnare et al. 1995; Burger et al. 2000), this gene is not transspliced (supported by cDNA PCR results, data not shown), and therefore, the gene pieces are translated as separate subunits that require co-assembly to form the functional protein structure.
Cohesin's association with and dissociation from chromosomes as well as its acetylation by Eco1 during S phase depends on regulatory subunits such as Wapl, Pds5 [27], and Scc3 [20,37] that bind the ring via its kleisin subunit as well as a separate Scc2/4 loading complex [6].
Fitting a set of small, separate subunits into a large map at low resolution is very difficult, unless information on subunit interfaces is available.
