Biochemical characterization of a new nicotinamidase from an unclassified bacterium thriving in a geothermal water stream microbial mat community. [PDF]
Nicotinamidases are amidohydrolases that convert nicotinamide into nicotinic acid, contributing to NAD+ homeostasis in most organisms. In order to increase the number of nicotinamidases described to date, this manuscript characterizes a nicotinamidase ...

Features of phospho- and amidohydrolases functioning in edaphotopes polluted by ore mill effluents
Influence of aerotechnogenic contamination of soils on activity of some hydrolytic enzymes of nitrogen and phosphorus cycles is examined. Biochemical mobilization of organophosphorous and nitrogen-bearing compounds in soils polluted by heavy metals is ...

Tackling Critical Catalytic Residues in Helicobacter pylori L-Asparaginase
Bacterial asparaginases (amidohydrolases, EC 3.5.1.1) are important enzymes in cancer therapy, especially for Acute Lymphoblastic Leukemia. They are tetrameric enzymes able to catalyze the deamination of L-ASN and, to a variable extent, of L-GLN, on ...

Structure-guided engineering of molinate hydrolase for the degradation of thiocarbamate pesticides.
Molinate is a recalcitrant thiocarbamate used to control grass weeds in rice fields. The recently described molinate hydrolase, from Gulosibacter molinativorax ON4T, plays a key role in the only known molinate degradation pathway ending in the formation ...

Stereochemical aspects of the nucleophilic attack in different classes of l-asparaginases
L-Asparaginases hydrolyze L-asparagine to L-aspartate with the release of ammonia. Currently, three completely unrelated structural classes of L-asparaginases are known, further subdivided into five types.
