RNA-Dependent Cysteine Biosynthesis in Bacteria and Archaea
mBio, 2017 The diversity of the genetic code systems used by microbes on earth is yet to be elucidated. It is known that certain methanogenic archaea employ an alternative system for cysteine (Cys) biosynthesis and encoding; tRNACys is first acylated with ...

Proceedings of the Japan Academy, Series B, 2008 In 1985, we reported that a bacterium, Mycoplasma capricolum, used a deviant genetic code, namely UGA, a "universal" stop codon, was read as tryptophan. This finding, together with the deviant nuclear genetic codes in not a few organisms and a number of mitochondria, shows that the genetic code is not universal, and is in a state of evolution.

The new (liberal) eugenics [PDF]
, 2013 Despite the Nazi horrors, in 1953 the new eugenics was founded, when Watson and Crick postulated the double helix of DNA as the basis of chemical heredity.

eLife, 2018 D-aminoacyl-tRNA deacylase (DTD) acts on achiral glycine, in addition to D-amino acids, attached to tRNA. We have recently shown that this activity enables DTD to clear non-cognate Gly-tRNAAla with 1000-fold higher efficiency than its activity on Gly ...

Analysis of codon usage pattern in Lonicera × heckrottii ‘Gold Flame’ based on chloroplast genome
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022 Codon usage bias (CUB) was a unique feature of the genome, and revealing chloroplast genome codon usage bias can provide useful information for the evolution of plant species.

Genetic code 1990. Outlook [PDF]
Experientia, 1990 The genetic code is evolving as shown by 9 departures from the universal code: 6 of them are in mitochondria and 3 are in nuclear codes. We propose that these changes are preceded by disappearance of a codon from coding sequences in mRNA of an organism or organelle. The function of the codon that disappears is taken by other, synonymous codons, so that

eLife, 2018 Organisms possessing genetic codes with unassigned codons raise the question of how cellular machinery resolves such codons and how this could impact horizontal gene transfer.
