Variability of Bioactive Glucosinolates, Isothiocyanates and Enzyme Patterns in Horseradish Hairy Root Cultures Initiated from Different Organs

open access: yesMolecules, 2019
Horseradish hairy root cultures are suitable plant tissue organs to study the glucosinolate−myrosinase−isothiocyanate system and also to produce the biologically active isothiocyanates and horseradish peroxidase, widely used in molecular ...

The Active Site Sulfenic Acid Ligand in Nitrile Hydratases Can Function as a Nucleophile [PDF]

open access: yes, 2014
Nitrile hydratase (NHase) catalyzes the hydration of nitriles to their corresponding commercially valuable amides at ambient temperatures and physiological pH.

Acrylamide Production Using Encapsulated Nitrile Hydratase from \u3cem\u3ePseudonocardia thermophila\u3c/em\u3e in a Sol–gel Matrix [PDF]

open access: yes, 2014
The cobalt-type nitrile hydratase from Pseudonocardia thermophila JCM 3095 (PtNHase) was successfully encapsulated in tetramethyl orthosilicate sol–gel matrices to produce a PtNHase:sol–gel biomaterial.

The IRAM-30m line survey of the Horsehead PDR: III. High abundance of complex (iso-)nitrile molecules in UV-illuminated gas [PDF]

open access: yes, 2013
Complex (iso-)nitrile molecules, such as CH3CN and HC3N, are relatively easily detected in our Galaxy and in other galaxies. We constrain their chemistry through observations of two positions in the Horsehead edge: the photo-dissociation region (PDR) and

A simple, efficient and rapid screening technique for differentiating nitrile hydratase and nitrilase producing bacteria

open access: yesBiotechnology Reports, 2019
Nitrile hydrolyzing enzymes catalyze the hydration of nitrile compounds to corresponding amides and acids. Bacteria, isolated from soil samples were screened for nitrile hydrolyzing enzymes by simple dye based 96 well plate and nesslerization method ...

3.7 billion year old biogenic remains

open access: yesCommunicative & Integrative Biology, 2017
3.7 Billion year old inclusions inside garnet crystals contain 13C depleted carbonaceous material consistent with biogenic origin. Additional evidence in the form of the other elements of life mainly O, N and P were found to be structural bound to this ...

Momentum Transfer Rate Constants for Collision of Cl-with Trans-Dichloroethylene and Para-Difluorobenzene [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used

Identification and Characterization of Three Epithiospecifier Protein Isoforms in Brassica oleracea

open access: yesFrontiers in Plant Science, 2019
Glucosinolates present in Brassicaceae play a major role in herbivory defense. Upon tissue disruption, glucosinolates come into contact with myrosinase, which initiates their breakdown to biologically active compounds.
