Crystal structure of carbon-nitrogen hydrolase from Helicobacter pylori G27. [PDF]
H. pylori carbon–nitrogen hydrolase was produced and crystallized, and its 2.1 Å resolution structure is reported.Carbon–nitrogen hydrolases (CNHs) are members of the diverse nitrilase superfamily of enzymes that facilitate cellular adaptation to environmental stress by metabolizing nitrogen, detoxifying xenobiotics and catabolizing environmentally ...

Thermotolerant D-Hydantoinases for Efficient and Stereoselective Intermediate Synthesis of (R)-3-Isobutylglutaric Acid Monoamide, a Key Intermediate in Pregabalin Production. [PDF]
We engineered thermo‐alkali‐stable D‐hydantoinases via mutagenesis (M63A/F65H/C317T) to resolve Pregabalin's challenging chiral splitting, achieving ee value > 97% for key intermediate (R)‐3‐isobutylglutaric acid monoamide (R‐IBM) synthesis under extreme conditions (pH 10, 70°C–80°C).

Penicillin Amidohydrolases in Fungal Autolysis [PDF]
AbstractThe production of penicillin G and penicillin V amidohydrolases or acylases (E.C.3.5.1.11) was studied during the autolysis of filamentous fungi in a mineral medium, and in the same medium with phenoxyacetic acid as inducer. In all the studied fungi, enzymes showing penicillin G and penicillin V amidohydrolase activities were found.

Structure of the Ergothioneine‐Biosynthesis Amidohydrolase EgtC [PDF]
AbstractThe ubiquitous sulfur metabolite ergothioneine is biosynthesized by oxidative attachment of a sulfur atom to the imidazole ring of Nα‐trimethylhistidine. Most actinobacteria, including Mycobacterium tuberculosis, use γ‐glutamyl cysteine as a sulfur donor. In subsequent steps the carbon scaffold of γ‐glutamyl cysteine is removed by the glutamine

Phenoxymethylpenicillin amidohydrolases from Penicillium chrysogenum [PDF]
A phenoxymethylpenicillin amidohydrolase which hydrolyses phenoxymethylpenicillin to 6‐aminopenicillanic acid (6‐APA) has been isolated from two species of Penicillium chrysogenum. The amidohydrolase had a molecular mass of approx. 42 kDa. Its activity with benzylpenicillin as substrate was only 1.5% of that with phenoxymethylpenicillin and it was ...

EFFECT OF PHYTOHORMONES ON UREASE ACTIVITY OF MARROW COTYLEDONS [PDF]
Urease (EC 3.5.1.5, urea amidohydrolase) was isolated from marrow cotyledons of 5-day old seedlings. The effect of exogenous phytohormones namely indolebutyric acid, naphthaleneacetic acid, indoleacetic acid, indolepropionic acid, indoleacetic acid and ...
