In plants, this enzyme exists in two distinct forms as a photosynthetic (pFNR) and as a heterotrophic (hFNR) form.
We demonstrate that human MIC26 exists in three distinct forms: (1) a glycosylated and secreted 55 kDa protein, (2) an ER/Golgi-resident form thereof, and (3) a non-glycosylated 22 kDa mitochondrial protein.
Disappearance of the tRNALeu should have abolished the ambiguous status of CUG codons, however the tRNACAGSer is recognized by both LeuRS and SerRS (see above), creating a serine tRNA that exists in 2 distinct forms, namely ser-tRNACAGSer (charged with serine) and leu-tRNACAGSer (charged with leucine).
PCNA exists in two distinct forms: replication-competent chromatin-bound form and chromatin unbound form, which is not involved in DNA synthesis [ 82].
SCA13 exists in distinct neurodegenerative and neurodevelopmental forms depending on which KCNC3 mutation is present (Waters et al., 2006).
Water also becomes glassy below Tg ≈ 130 K and in that region can exist in two distinct amorphous forms (i.e., it is "polymorphous")2.
Mammalian SWI/SNF chromatin remodelling complexes exist in three distinct, final-form assemblies: canonical BAF (cBAF), PBAF and a newly characterized non-canonical complex (ncBAF).
Isoforms of VEGF-A exist in two distinct families, formed by alternative mRNA splicing [ 7].
As described above, HLA-G can exist in similar forms, but possesses unique cysteine residues distinct from other MHCI, including Cys42, which is involved in disulfide-linked dimer formation without any conformational changes.
The gram positive bacterium Bacillus anthracis exists in two morphologically distinct forms, the metabolically active cell, and the dormant spore.
