Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean [PDF]
, 2013 Drought stress is a major factor limiting symbiotic nitrogen fixation (NF) in soybean crop production. However, the regulatory mechanisms involved in this inhibition are still controversial.

Regulation of N-Acetylkanamycin Amidohydrolase in the Idiophase in Kanamycin Fermentation [PDF]
Agricultural and Biological Chemistry, 1976 Formation of N-acetylkanamycin amidohydrolase (NAKA) in a strain of Streptomyces kanamyceticus proceeded in parallel with the increase of both kanamycin (KM) and N-acetylkanamycin (NAK) in the initial period. NAKA formation then suddenly began to decrease in NAK but KM continued to increase before reaching a maximum level.

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium
Advanced Science, Volume 13, Issue 7, 3 February 2026.The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

Bacterial amidohydrolases and modified 5-fluorocytidine compounds: Novel enzyme-prodrug pairs.
PLoS ONE, 2023 Gene-directed enzyme prodrug therapy is an emerging strategy for cancer treatment based on the delivery of a gene that encodes an enzyme that is able to convert a prodrug into a potent cytotoxin exclusively in target cancer cells.

Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics. [PDF]
, 2019 The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria ...

Creatinine biosensors: principles and designs [PDF]
, 2000 Creatinine biosensors, based on both potentiometric and amperometric devices, have been created. However, there are significant problems still to be addressed, including the balance between sensitivity and selectivity, interference rejection and sensor

Microbial Biotechnology, Volume 19, Issue 2, February 2026.Paenarthrobacter are specialists in degrading the fungicide iprodione. We showed that this trait has evolved through gene duplication of ipaH and ddaH genes, being in the core genome of paenarthrobacters, and further genetic optimisation, with different strains being at different evolution stages depending on their prior exposure to iprodione ...

A gold standard set of mechanistically diverse enzyme superfamilies [PDF]
, 2006 Superfamily and family analyses provide an effective tool for the functional classification of proteins, but must be automated for use on large datasets. We describe a 'gold standard' set of enzyme superfamilies, clustered according to specific sequence,

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.The Antarctic Dietzia and Pusillimonas isolates were tested for bioremediation applications. Genomic analyses revealed the potential to degrade complex organic compounds, potential virulence factors and resistance genes. Physiological assays showed a wide range of adaptation to abiotic factors and sensitivity to different groups of antibiotics ...

Untersuchungen zum Ursprung der Substratspezifität von Enzymen der Amidohydrolase‐Superfamilie
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Umfassende Analysen zweier Enzymklassen aus der Amidohydrolase‐Superfamilie (AHS) ergaben, dass die Katalyse über eine 1,4‐ bzw. 1,6‐nukleophile konjugierte Addition abläuft und diese Eigenschaft die Substratspezifität bestimmt. Obwohl alle Substrate und Produkte vollständig achiral sind, führt dieser mechanistische Unterschied zu einer invertierten ...
