Ribosomes are multicomponent macromolecular particles and
are essential for the survival of cells in all organisms. The ribosome's
universal function is to catalyze polypeptide synthesis through
translation of mRNA transcripts. Ribosomes from Escherichia coli,
eubacterial organisms, have a sedimentation coefficient of 70S and are
composed of 30S and 50S ribonucleoprotein...
The ribosome is a central component of the protein
synthetic apparatus. It is a macromolecular complex of
protein and RNA. Although much progress has been made in
understanding the functional role of the proteins in this
particle, little is known of the functional role which
the RNA plays. Naturally occurring...
Ribosomes are ribonucleoprotein particles that are essential for
the process of protein synthesis in all living systems. Escherichia
coli, eubacterial organisms, have ribosomes which display a 70S
sedimentation coefficient. They are formed by the association of two
ribonucleoprotein subunits which sediment at 50S and 30S. The 30S
subunit is a...
Ribosomes are intricate macromolecular complexes which are a major
element of the protein biosynthetic machinery in all life forms. In
Escherichia coli they contain about 50 distinct proteins and 3
ribosomal RNAs. The small 30S ribosomal subunit in E. coli
incorporates 21 proteins and a 16S rRNA. The 16S rRNA...
Escherichia coli 16S-like ribosomal RNAs from
eubacterial, archaebacterial and eukaryotic organisms have
several universally conserved sequence zones which are
proposed to be single-stranded. A clear function for all
of these regions has not yet been defined. To evaluate the
roles of these sequence zones in protein synthesis,
knowledge of their...
