Review of Lysine Metabolism with a Focus on Humans.
Journal of NutriLife, 2020 Lysine cannot be synthesized by most higher organisms and, therefore, is an indispensable amino acid (IAA) that must be consumed in adequate amounts to maintain protein synthesis.

Suppressors of lysine codons may be misacylated lysine tRNAs [PDF]
Journal of Bacteriology, 1983 We describe a novel class of missense suppressors that read the codons for lysine at two positions (211 and 234) in the trpA polypeptide of Escherichia coli. The suppressor mutations are highly linked to lysT, a gene for lysine tRNA. The results suggest that the suppressors are misacylated lysine tRNAs that carry glycine or alanine.

Dietary lysine requirement of adult lambari ( Astyanax altiparanae ) (Garutti and Britski, 2000)
Revista Brasileira de Zootecnia, 2018 A 90-day feeding trial was conducted to estimate the dietary lysine requirement of adult lambari ( Astyanax altiparanae ), based on growth performance, whole-body composition, muscle development, and aspartate aminotransferase (AST) and alanine ...

A computational model for histone mark propagation reproduces the distribution of heterochromatin in different human cell types [PDF]
PLoS ONE 8(9): e73818, 2013 Chromatin is a highly compact and dynamic nuclear structure that consists of DNA and associated proteins. The main organizational unit is the nucleosome, which consists of a histone octamer with DNA wrapped around it. Histone proteins are implicated in the regulation of eukaryote genes and they carry numerous reversible post-translational modifications

Effect of bet missense mutations on bromodomain function, inhibitor binding and stability [PDF]
, 2016 Lysine acetylation is an important epigenetic mark regulating gene transcription and chromatin structure. Acetylated lysine residues are specifically recognized by bromodomains, small protein interaction modules that read these modification in a ...

Entropic stabilization of proteins and its proteomic consequences [PDF]
, 2005 We report here a new entropic mechanism of protein thermostability due to residual dynamics of rotamer isomerization in native state. All-atom simulations show that Lysines have much greater number of accessible rotamers than Arginines in folded states of proteins.

Antitumor effect of lysine-isopeptides [PDF]
, 2002 Isopeptides (ε-peptides) of lysine, with a given Mw and low polydispersity (10–400 units), were synthesized to study the relationship between their chemical structure and biological effect.
