Regulatory RNAs in archaea: first target identification in Methanoarchaea [PDF]
Biochemical Society Transactions, 2013 sRNAs (small non-coding RNAs) representing important players in many cellular and regulatory processes have been identified in all three domains of life. In Eukarya and Bacteria, functions have been assigned for many sRNAs, whereas the sRNA populations in Archaea are considerably less well characterized.

Identification of an Archaeal 2-Hydroxy Acid Dehydrogenase Catalyzing Reactions Involved in Coenzyme Biosynthesis in Methanoarchaea [PDF]
Journal of Bacteriology, 2000 ABSTRACT Two putative malate dehydrogenase genes, MJ1425 and MJ0490, from Methanococcus jannaschii and one from Methanothermus fervidus were cloned and overexpressed in Escherichia coli , and their gene products were tested for the ability to catalyze ...

Journal of Microbiology, Immunology and Infection, 2013 β-amino acids play important biological roles as precursors in the biosynthesis of antibiotics, anticancer agents, neurotransmitters, and other high molecular weight polymers. Microbial cells and enzymes from extreme environments offer new opportunities for biocatalysis and biotransformations as a result of their extreme stability.
