From Wikipedia, the free encyclopedia
Archaeal translation is the process by which
messenger RNA is
translated into
proteins in
archaea . Not much is known on this subject, but on the protein level it seems to resemble
eukaryotic translation .
Most of the
initiation ,
elongation , and
termination factors in archaea have homologs in eukaryotes.
[1]
Shine-Dalgarno sequences only are found in a minority of genes for many phyla, with many leaderless mRNAs probably initiated by scanning.
[2]
[3]
[4] The process of
ABCE1 ATPase-based recycling is also shared with eukaryotes.
[5]
Being a
prokaryote without a nucleus, archaea do perform transcription and translation at the same time like bacteria do.
