Eubacteria

Definition

noun, singular: eubacterium

Literally means true bacteria, which includes all bacteria except for archaebacteria.


Supplement

These bacteria form the domain Bacteria, previously called domain Eubacteria. It is one of the three domain systems, the other two being domain Archaeabacteria (now Archaea) and domain Eukarya (the eukaryotes)

Eubacteria are prokaryotic organisms, as characterized by the lack of a membrane-enclosed nucleus, predominantly unicellular, with DNA in single circular chromosome, and have peptidoglycan on cell wall when present. They include most of the familiar bacteria of medical and economic importance such as E. coli, Staphylococcus , Salmonella, Lactobacillus, Nitrosomonas, Streptomyces, etc.


Word origin: 1935–40; eu: in scientific coinages, means “true, genuine” + bacteria.

Synonym: (true) bacteria.
Compare: Archaebacteria.
See also: Monera, prokaryote.

Re: origin of eukaryotic cell

... itself. If sequence similarity is any measure of evolutionary relatedness then the divergence in FtsZ and tubulin will place the archea and eubacteria away from eukarya. No doubt there are lot of evidences to support the merger theory but what has not been clearly established is the origin ...

origin of eukaryotic cell

... full text PDFs available for free download. [edit] More specific to your question, if it is not in fact present in any archaea but is present in eubacteria, is there any reason why FtsA genes couldn't have been inherited from the eubacterial endosymbiont via horizontal gene transfer along with ...

origin of eukaryotic cell

... could have been their ancesters. What I gathered in some literature is that eukaryote may have evolved by a merger of an archebacteria with an eubacteria. The evidence quoted was that a protein FtsZ ( which is involved in bacterial cell division) is similar in its sequence to tubulin - the ...
