AMINOHYDROLASES ACTING ON ADENINE, ADENOSINE AND THEIR DERIVATIVES [PDF]

open access: yesBiomedical Papers, 2007
Adenine and adenosine-acting aminohydrolases are important groups of enzymes responsible for the metabolic salvage of purine compounds. Several subclasses of these enzymes have been described and given current knowledge of the full genome sequences of many organisms, it is possible to identify genes encoding these enzymes and group them according to ...

L-asparaginase from Dickeya chrysanthemi: expression, purification and cytotoxicity assessment

open access: yes, 2022
Microbial L-asparaginases are aminohydrolases that hydrolyze L-asparagine to L-aspartate. They are used to treat acute lymphoblastic leukemia and Hodgkin’s lymphomas and in food industries. Increasing demand for L-ASNases is therefore needed.

The effect of renal stones on serum adenosine aminohydrolase and AMP-aminohydrolase in Malaysia

open access: yesAsian Pacific Journal of Tropical Biomedicine, 2015
AbstractObjectiveTo verify possible associations between adenosine aminohydrolase (ADA) and AMP-aminohydrolase (AMPDA) to E3 SUMO-protein ligase NSE2 (NSMCE2) in patients with renal stones. And to isolate, purify and characterize ADA in patients with renal stones and healthy group.MethodsA total of 60 renal stones patients and 50 control were enrolled ...

The Role of the Sulphydryl Groups of Spleen Deoxycytidylate Aminohydrolase [PDF]

open access: yesEuropean Journal of Biochemistry, 1974
The relation between sulphydryl groups and enzyme activity, and between sulphydryl groups and changes of conformation of the enzyme molecule caused by allosteric effectors has been studied in deoxycytidylate aminohydrolase with a homogeneous preparation of the spleen enzyme.

The “Neutral” Hydrolysis of Simple Carboxylic Esters in Water and the Rate Enhancements Produced by Acetylcholinesterase and Other Carboxylic Acid Esterases

open access: yes, 2016
Experiments at elevated temperatures permit the determination of rate constant and thermodynamic activation parameters for the neutral hydrolysis of the neurotransmitter acetylcholine in water. At 25 °C, the extrapolated rate constant for the uncatalyzed

Safety evaluation of the food enzyme AMP deaminase from the genetically modified Bacillus subtilis strain CCTCC M 2023264

open access: yesEFSA Journal, Volume 24, Issue 4, April 2026.
Abstract The food enzyme AMP deaminase (AMP aminohydrolase; EC 3.5.4.6) is produced with the genetically modified Bacillus subtilis strain CCTCC M 2023264 by Angel Yeast Co., Ltd. The production strain of the food enzyme contains multiple copies of three acquired antimicrobial resistance genes, therefore it does not fulfil the requirements of the ...

The Crystal Structure of Human Transport and Golgi Organization 2 Homolog (TANGO2) Protein Reveals an αββα‐Fold Arrangement

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 2, Page 515-528, February 2026.
ABSTRACT Transport and Golgi Organization 2 Homolog (TANGO2) protein deficiency disorder (TDD) is a rare autosomal recessive disorder characterized by multi‐systemic abnormalities and significant phenotypic variability including neurodevelopmental delay, seizures, intermittent ataxia, hypothyroidism, rhabdomyolysis, life‐threatening metabolic ...

On the Origin of Substrate Specificity of Enzymes from the Amidohydrolase Superfamily

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Comprehensive analyses of two enzyme classes from the amidohydrolase superfamily (AHS) revealed that catalysis proceeds either via 1,4 or 1,6 nucleophilic conjugate addition and that this property defines substrate specificity. Moreover, although all substrates and products are entirely achiral, this mechanistic difference results in an inverted ...

Safety evaluation of an extension of use of the food enzyme leucyl aminopeptidase from the non‐genetically modified Lichtheimia ramosa strain AE‐PER

open access: yesEFSA Journal, Volume 23, Issue 12, December 2025.
Abstract The food enzyme leucyl aminopeptidase (AMP aminohydrolase; EC 3.4.11.1) is produced with the non‐genetically modified Lichtheimia ramosa strain AE‐PER by Amano Enzyme Inc. A safety evaluation of this food enzyme was made previously, in which EFSA concluded that this food enzyme did not give rise to safety concerns when used in five food ...
