Blood amino acids concentration during insulin induced hypoglycemia in rats: the role of alanine and glutamine in glucose recovery

open access: yes, 2015
Our purpose was to determine the blood amino acid concentration during insulin induced hypoglycemia (IIH) and examine if the administration of alanine or glutamine could help glycemia recovery in fasted rats.

Structure-Function Studies of Nicotinic Acetylcholine Receptors Using Unnatural Amino Acids [PDF]

open access: yes, 2012
This dissertation primarily describes structure-function studies of the nicotinic acetylcholine receptors (nAChRs). These studies use a combination of unnatural amino acid mutagenesis and electrophysiology to determine the specific molecular interactions

Enhanced γ-aminobutyric acid levels promote degeneration of silk glands following spermidine supplementation in Bombyx mori

open access: yesAmino Acids
Silk glands are modified labial glands that produce silk which has immense commercial importance. Silk is extruded out in liquid form after which the glands undergo autophagy and apoptosis during larval to pupal transition.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Amino-acids in soil

open access: yes, 1950
ALTHOUGH the protein nature of at least one-third of the organic nitrogen of soil has been established, very little is known of the amino-acid composition of this protein material. The isolation of amino-acids from soil hydrolysates is rendered difficult

Post-translational modifications of ezrin: a crucial regulator for diseases

open access: yesAmino Acids
Ezrin is a crucial structural protein that connects the plasma membrane to the actin cytoskeleton to maintain cell shape, adhesion, and motility. Post-translational modifications (PTMs) play a key role in the regulation of various biological functions ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Lysine malonylation as a therapeutic target: implications for metabolic, inflammatory, and oncological disorders

open access: yesAmino Acids
Lysine malonylation (Kmal) is an emerging posttranslational modification (PTM) intricately linked to cellular metabolism and disease pathogenesis. This review explores the regulatory mechanisms of Kmal, emphasizing the role of malonyl-CoA as its donor ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Ionization characteristics of amino acids in direct analysis in real time mass spectrometry.

open access: yes, 2014
The positive and negative ionization characteristics of 20 different α-amino acids were investigated using Direct Analysis in Real Time (DART) mass spectrometry. Almost all of the amino acids M were ionized to generate the (de)protonated analytes [M ± H](
