Cystathionine β-Synthase Is Necessary for Axis Development in Vivo

Frontiers in Cell and Developmental Biology, 2018
The cystathionine ß-synthase (CBS) is a critical enzyme in the transsulfuration pathway and is responsible for the synthesis of cystathionine from serine and homocysteine. Cystathionine is a precursor to amino acid cysteine.

Plasma methionine concentrations and incidence of hypermethioninemic encephalopathy during infancy in a large cohort of 36 patients with classical homocystinuria in the Republic of Ireland

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

Isolation and Characterization of Methionine-Independent Clones from Methionine-Dependent Cancer Cells [PDF]

, 2019
Unlike normal cells, transformed cells are unable to grow when methionine in the growth media is restricted. Reversion to methionine independence is a rare event in transformed and malignant cells.

Bigheaded Carp-Based Meal as a Sustainable and Natural Source of Methionine in Feed for Ecological and Organic Poultry Production

Journal of Applied Poultry Research, 2019
SUMMARY: High-quality protein feeds are needed in ecological and organic poultry production. Feeds that are rich in methionine (MET) are particularly important because synthetic amino acids are generally prohibited in organic livestock production ...

Synthesis of Two Stable Nitrogen Analogues of S-Adenosyl-l-methionine

, 2016
Homochiral syntheses of two stable nitrogen analogues of S-adenosyl-l-methionine (AdoMet) are described. In the first analogue, AzaAdoMet, the sulfonium center of AdoMet, is replaced by an N-methyl moiety whose pKa is 7.08.

Crystal structure of a new homochiral one-dimensional zincophosphate containing l-methionine

Acta Crystallographica Section E: Crystallographic Communications, 2015
catena-Poly[[(l-methionine-κO)zinc]-μ3-(hydrogen phosphato)-κ3O:O′:O′′], [Zn{PO3(OH)}(C5H11NO2S)]n, a new one-dimensional homochiral zincophosphate, was hydrothermally synthesized using l-methionine as a structure-directing agent.

Genome-Based Metabolic Reconstruction Unravels the Key Role of B12 in Methionine Auxotrophy of an Ortho-Phenylphenol-Degrading Sphingomonas haloaromaticamans

Frontiers in Microbiology, 2020
Auxotrophy to amino acids and vitamins is a common feature in the bacterial world shaping microbial communities through cross-feeding relations. The amino acid auxotrophy of pollutant-degrading bacteria could hamper their bioremediation potential ...
