Study of complexes of cadmium with some L-amino acids and vitamin-C by voltammetric technique

Eclética Química, 2018
Voltammetric technique was used to study the binary and ternary complexes of cadmium with L-amino acids and vitamin-C (L-ascorbic acid) at pH =7.30 ± 0.01, μ = 1.0M KNO3 at 25ºC and 35ºC.

Two techniques of age estimation in cetaceans: GLGs in teeth and earplugs, and measuring the AAR rate in eye lens nucleus

NAMMCO Scientific Publications, 2017
The ages of three species of cetaceans were estimated by counting the growth layer groups (GLG) and measuring the aspartic acid racemization rate (kAsp) by what is referred to as the Aspartic Acid Racemization (AAR) technique.

Crystal structures of the elusive Rhizobium etli l-asparaginase reveal a peculiar active site

Nature Communications, 2021
L-asparaginases catalyse the hydrolysis of L-asparagine to L-aspartic acid and ammonia. Here, the authors present high resolution crystal structures of Rhizobium etli L-asparaginase that contains a Zn2+ binding site without a catalytic role and discuss ...

A Novel Inhibitor of β-Glucuronidase: l-Aspartic Acid [PDF]

Pediatric Research, 2001
Infants who consume casein hydrolysate formula have been shown to have lower neonatal jaundice levels than infants who consume routine formula or breast milk. Because casein hydrolysate has been shown to contain a beta-glucuronidase inhibitor, one possible mechanism to explain this finding is blockage of the enterohepatic circulation of bilirubin by a ...

Effect of insect cuticular compounds on appressorium formation and metabolic activity in Metarhizium anisopliae

Frontiers in Microbiology
The rate of appressoria formation following conidial germination in Metarhizium anisopliae is closely associated with its pathogenicity. This study investigated the effects of insect cuticular compounds on the formation and metabolism in M. anisopliae by

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS 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 ...
