Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

NH2-terminal amino acids of the serum lipoproteins of normal and hypercholesterolemic rabbits*

Journal of Lipid Research, 1960
Aspartic acid is the major and glutamic acid and serine are minor NH2-terminal amino acids of the lipoproteins of rabbit serum. No NH2-terminal amino acids other than these are found after prolonged cholesterol feeding.

A comparison between incremental lines of cementum and aspartic acid racemization in age estimation: histological and biochemical study

Egyptian Journal of Forensic Sciences, 2023
Background Age estimation is a vital aspect of the identification of an individual in forensic science. Teeth are one of the toughest structures in the human body and generally survive postmortem destruction.

INTERACTION OF ASPARTATE AMINOTRANSFERASE WITH AMINO ACIDS [PDF]

Biochemical Journal, 1965
1. The capacity of various amino acids to convert the pyridoxal form of aspartate aminotransferase into the pyridoxamine form has been investigated. 2. Glutamate has the highest converting capacity; aspartate, alpha-aminopimelate, alpha-aminoadipate and other amino acids follow. 3. The converting capacity of the various amino acids assayed is connected

The conversion of citrulline to arginine in kidney [PDF]

, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

Repositioning the Catalytic Triad Aspartic Acid of Haloalkane Dehalogenase: Effects on Stability, Kinetics, and Structure [PDF]

, 1997
Haloalkane dehalogenase (DhlA) catalyzes the hydrolysis of haloalkanes via an alkyl-enzyme intermediate. The covalent intermediate, which is formed by nucleophilic substitution with Asp124, is hydrolyzed by a water molecule that is activated by His289 ...

Novel highly-soluble peptide-chitosan polymers: Chemical synthesis and spectral characterization [PDF]

, 2006
Novel water-soluble polymers, N-(gamma-propanoyl-valin)-chitosan and N-(gamma-propanoyi-aspartic acid)-chitosan, were synthesized by reaction of low molecular weight chitosan with N-alpha-(3-bromopropanoyl)-valine and N-alpha-(3-bromopropanoyl)-aspartic ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

Advanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...
