Immobilization of transaminase from Bacillus licheniformis on copper phosphate nanoflowers and its potential application in the kinetic resolution of RS-α-methyl benzyl amine

open access: yesBioresources and Bioprocessing, 2021
This study reports the isolation and partial purification of transaminase from the wild species of Bacillus licheniformis. Semi-purified transaminase was immobilized on copper nanoflowers (NFs) synthesized through sonochemical method and explored it as a

Coordinated Slowing of Metabolism in Enteric Bacteria under Nitrogen Limitation: A Perspective [PDF]

open access: yesarXiv, 2001
It is natural to ask how bacteria coordinate metabolism when depletion of an essential nutrient limits their growth, and they must slow their entire rate of biosynthesis. A major nutrient with a fluctuating abundance is nitrogen. The growth rate of enteric bacteria under nitrogen-limiting conditions is known to correlate with the internal concentration

Transaminase activity in human blood.

open access: yesJournal of Clinical Investigation, 1955
Enzymatic transamination consists of the enzyme catalyzed reversible transfer of the alpha amino nitrogen of an amino acid to an alpha-keto acid with the synthesis of a second amino acid and a second alpha-keto acid.

Salt‐Compact Albumin as a New Pure Protein‐based Biomaterials: From Design to In Vivo Studies

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A new class of materials built entirely of native albumin protein is designed using a simple protocol based on salt‐assisted compaction, breaking with current crosslinking strategies. This green process leads, surprisingly, to water‐insoluble handable materials with high preservation of their native protein structures and Young's modulus close to that ...

Serum Transaminase in Duchenne Dystrophy

open access: yesPediatric Neurology Briefs, 2011
Researchers at Children’s Hospital Boston, MA, have shown a linear relationship between serum CPK and serum ALT and AST and a logarithmic relationship between serum enzyme levels and age for boys with Duchenne (n=46) or Becker (n=9) muscular dystrophy ...

Acute vigabatrin-phenobarbitone-interaction on exploratory behaviour of rats [PDF]

open access: yes, 1996
Vigabatrin (gamma-vinyl GABA) is an irreversible inh:bitor of the enzyme GABA-transaminase (GABA-T) which is responsible for the catabolism of the major inhibitory neurotransmitter gamma- aminobutyric acid (GABA) in the brain. Vigabatrin causes a several

A Regio- and Stereoselective ω-Transaminase/Monoamine Oxidase Cascade for the Synthesis of Chiral 2,5-Disubstituted Pyrrolidines

open access: yesAngewandte Chemie, 2014
Biocatalytic approaches to the synthesis of optically pure chiral amines, starting from simple achiral building blocks, are highly desirable because such motifs are present in a wide variety of important natural products and pharmaceutical compounds ...

Carbon‐Based Flexible Electrode for Efficient Electrochemical Generation of Reactive Chlorine Species in Tumor Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A flexible electrode loaded with a carbon nanowire network (CC@C‐NWN) is developed for electrochemically generating reactive chlorine species (RCS) from abundant chloride ions in body fluids for tumor therapy. CC@C‐NWN enhances chlorine evolution, inducing redox dysregulation and synergistic apoptosis‐ferroptosis in tumor cells.
