Quantitative analysis of in vivo methionine oxidation of the human proteome
bioRxiv, 2019 The oxidation of methionine is an important posttranslational modification of proteins with numerous roles in physiology and pathology. However, the quantitative analysis of methionine oxidation on a proteome-wide scale has been hampered by technical ...

Effect of Methionine Restriction on IGF-1 Gene Expression in Breast Muscle of Japanese Quail [PDF]
مجله بیوتکنولوژی کشاورزی, 2016 In the present study to investigate the effect of dietary methionine restriction on IGF-1 gene expression in breast muscle of Japanese quail, 200 pieces of the birds were randomly divided into two different dietary groups containing recommended ...

Antioxidants, 2018 Cysteine and methionine residues are the amino acids most sensitive to oxidation by reactive oxygen species. However, in contrast to other amino acids, certain cysteine and methionine oxidation products can be reduced within proteins by dedicated ...

JIMD Reports, 2019 Background Classical homocystinuria is an autosomal recessive disorder caused by profound cystathionine β‐synthase deficiency. Its biochemical hallmarks are high concentrations of plasma homocyst(e)ine and methionine. Clinical manifestations include lens

MUTANTS OF ESCHERICHIA COLI REQUIRING METHIONINE OR VITAMIN B12
Journal of Bacteriology, 1950 The penicillin method (Davis, 1948; Lederberg and Zinder, 1948) has permitted convenient isolation of auxotrophicl mutants of Escherichia coli with specific growth requirements for most of the known water-soluble vitamins, as well as amino acids, purines,

Propagation of Fluctuations in Biochemical Systems, I: Linear SSC Networks [PDF]
arXiv, 2005 We investigate the propagation of random fluctuations through biochemical networks in which the concentrations of species are large enough so that the unperturbed problem is well-described by ordinary differential equation. We characterize the behavior of variance as fluctuations propagate down chains, study the effect of side chains and feedback loops,

arXiv, 2013 Present day data allow significant reconsideration of ideas on mechanisms underlying the degeneracy in the genetic code. Here a hypothesis is presented which links the degeneracy to possible conformational alterations in the codon-anticodon duplex. This enables explanation of Rumer symmetry in the table of the genetic code, coding of methionine and ...

The Biosynthetic Order of Amino Acid Addition to the Genetic Code [PDF]
arXiv, 2002 The previously formulated model for the evolution of the genetic code was shown to clarify why base triplets of some precursor amino acids differ by a single base from product amino acid codons, while others show less homology. First, the model indicated that the direction of code evolution changed on expansion from the N-fixers code (stage 2).

N‐Terminal Methionine Processing
Current Protocols in Protein Science, 2017 Protein synthesis is initiated by methionine in eukaryotes and by formylmethionine in prokaryotes. N‐terminal methionine can be co‐translationally cleaved by the enzyme methionine aminopeptidase (MAP). When recombinant proteins are expressed in bacterial

Early step-down weaning of dairy calves from a high milk volume with glutamine supplementation
Journal of Dairy Science, 2022 : Weaning dairy calves from a high milk volume (≥8.0 kg/d) can negatively affect the growth and welfare even if it is performed in a step-down manner. Supplementation of Gln improved gut development of preweaning calves and mitigated weaning stresses of ...
