The non-canonical CTD of RNAP-II is essential for productive RNA synthesis in Trypanosoma brucei. [PDF]
The carboxy-terminal domain (CTD) of the largest subunit (RPB1) of RNA polymerase II (RNAP-II) is essential for gene expression in metazoa and yeast. The canonical CTD is characterized by heptapeptide repeats.

Insufficient mixing in large-scale bioreactors provokes gradient zones of substrate, dissolved oxygen (DO), pH, and other parameters. E. coli responds to a high glucose, low oxygen feeding zone with the accumulation of mixed acid fermentation products ...

Xenogeneic, extracorporeal liver perfusion in primates improves the ratio of branched-chain amino acids to aromatic amino acids (Fischer's ratio) [PDF]
In fulminant hepatic failure (FHF), the development of hepatic encephalopathy is associated with grossly abnormal concentrations of plasma amino acids (PAA).

Recombinant Macrocyclic Lanthipeptides Incorporating Non-Canonical Amino Acids [PDF]
Nisin is a complex lanthipeptide that has broad spectrum antibacterial activity. In efforts to broaden the structural diversity of this ribosomally synthesized lantibiotic, we now report the recombinant expression of Nisin variants that incorporate noncanonical amino acids (ncAAs) at discrete positions.

Phase-separation propensity of non-ionic amino acids in peptide-based complex coacervation systems [PDF]
Uncovering the sequence-encoded molecular grammar that governs the liquid–liquid phase separation (LLPS) of proteins is a crucial issue to understand dynamic compartmentalization in living cells and the emergence of protocells. Here, we present a model

Development of Multivalent Conjugates with a Single Non‐Canonical Amino Acid
AbstractProteins represent powerful biomacromolecules due to their unique functionality and broad utility both in the cell and in non‐biological applications. The genetic encoding of non‐canonical amino acids (ncAAs) facilitates functional diversification of these already powerful proteins.

The genetic incorporation of thirteen novel non-canonical amino acids [PDF]
Thirteen novel non-canonical amino acids were synthesized and tested for suppression of an amber codon using a mutant pyrrolysyl-tRNA synthetase–tRNAPylCUA pair.

In this paper, we present a novel, “single experiment” methodology based on genetic engineering of metabolic pathways for direct intracellular production of non-canonical amino acids from simple precursors, coupled with expanded genetic code.

Expanding the genetic code of Salmonella with non-canonical amino acids [PDF]
AbstractThe diversity of non-canonical amino acids (ncAAs) endows proteins with new features for a variety of biological studies and biotechnological applications. The genetic code expansion strategy, which co-translationally incorporates ncAAs into specific sites of target proteins, has been applied in many organisms. However, there have been only few
