Homology
Between
Mitoribosomes
and
Bacterial
Ribosomes - To support the theory of the endosymbiotic origin of mitochondria several homologies between the protein synthesis systems of mitochondria and bacteria have been cited.
The diversity of mitoribosomal types is, however, so great that it is not possible to consider mitoribosomes homologous to bacterial ribosomes solely on the basis of size or S values.
A
number
of
homologies,
however,
do
exist
between
the
two
types
of
ribosomes,
which
are
not
found
in
cytoribosomes
of
higher
cells.
These include:
1) Suceptibility to antibiotics like chloramphenicol, erythromycin, tylosin, venanamycin, etc.
