Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]
, 2013 Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Magnesium ions mediate ligand binding and conformational transition of the SAM/SAH riboswitch
Communications Biology, 2023 The SAM/SAH riboswitch binds S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) with similar affinities. Mg2+ is generally known to stabilize RNA structures by neutralizing phosphates, but how it contributes to ligand binding and conformational ...

Serum S-adenosylmethionine, but not methionine, increases in response to overfeeding in humans [PDF]
, 2016 Background: Plasma concentration of the methyl donor S-adenosylmethionine (SAM) is linearly associated with body mass index (BMI) and fat mass. As SAM is a high-energy compound and a sensor of cellular nutrient status, we hypothesized that SAM would ...

Copper ions inactivate S-adenosylhomocysteine hydrolase
Chinese Science Bulletin, 2002 S-adenosylhomocysteine (AdoHcy) hydrolase is an enzyme that regulates biomethylation and some other physiological processes. Recombinant AdoHcy hydrolase was overexpressed inE. coli JM109 and purified with ion exchange and gel filtration chromatographies.

Inhibition of sterol transmethylation by S-adenosylhomocysteine analogs [PDF]
Journal of Bacteriology, 1981 Structural analogs of S-adenosylhomocysteine were tested in vitro for inhibition of the yeast S-adenosylmethionine:delta 24-sterol-C-methyltransferase enzyme. A wide inhibitory range by these compounds was observed, suggesting which structural features of the parent compound are important for binding to the enzyme.
