  2. Prokaryote - Wikipedia

    en.wikipedia.org/wiki/Prokaryote

    The cellular components of prokaryotes are not enclosed in membranes within the cytoplasm, like eukaryotic organelles.Bacteria have microcompartments, quasi-organelles enclosed in protein shells such as encapsulin protein cages, [4] [5] while both bacteria and some archaea have gas vesicles.

  3. FtsZ - Wikipedia

    en.wikipedia.org/wiki/FtsZ

    FtsZ is a prokaryotic homologue of the eukaryotic protein tubulin. The initials FtsZ mean " F ilamenting t emperature- s ensitive mutant Z ." The hypothesis was that cell division mutants of E. coli would grow as filaments due to the inability of the daughter cells to separate from one another.

  4. Prokaryotic ubiquitin-like protein - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_ubiquitin-like...

    Mpa delivers the substrate protein to the proteasome for degradation by coupling of ATP hydrolysis. The discovery of Pup indicates that like eukaryotes, bacteria may use a small-protein modifier to control protein stability. The Pup gene encodes a 64–amino acid protein with a molecular size of about 6.9 kDa. [3]

  5. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. [2] The genetic material is freely found in the cytoplasm. Prokaryotes can carry extrachromosomal DNA elements called plasmids, which are

  6. Ubiquitin - Wikipedia

    en.wikipedia.org/wiki/Ubiquitin

    Ubiquitin is a small protein that exists in all eukaryotic cells. It performs its myriad functions through conjugation to a large range of target proteins. A variety of different modifications can occur. The ubiquitin protein itself consists of 76 amino acids and has a molecular mass of about 8.6 kDa.

  7. Protein - Wikipedia

    en.wikipedia.org/wiki/Protein

    The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation, whereas peptide is generally reserved for a short amino acid oligomers often lacking a stable 3D structure. But the boundary between the two is not well ...

  8. Proteome - Wikipedia

    en.wikipedia.org/wiki/Proteome

    The genomes of viruses and prokaryotes encode a relatively well-defined proteome as each protein can be predicted with high confidence, based on its open reading frame (in viruses ranging from ~3 to ~1000, in bacteria ranging from about 500 proteins to about 10,000). [15]

  9. Prokaryotic small ribosomal subunit - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_small...

    The 30S subunit is an integral part of mRNA translation.It binds three prokaryotic initiation factors: IF-1, IF-2, and IF-3. [3]A portion of the 30S subunit (the 16S rRNA) guides the initiating start codon (5′)-AUG-(3′) of mRNA into position by recognizing the Shine-Dalgarno sequence, a complementary binding site about 8 base pairs upstream from the start codon.
