The Molybdenum Cofactor [PDF]

open access: yesJournal of Biological Chemistry, 2013
The transition element molybdenum needs to be complexed by a special cofactor to gain catalytic activity. Molybdenum is bound to a unique pterin, thus forming the molybdenum cofactor (Moco), which, in different variants, is the active compound at the catalytic site of all molybdenum-containing enzymes in nature, except bacterial molybdenum nitrogenase.

Genome-Scale Mining of Acetogens of the Genus Clostridium Unveils Distinctive Traits in [FeFe]- and [NiFe]-Hydrogenase Content and Maturation

open access: yesMicrobiology Spectrum, 2022
Knowledge of the organizational and functional properties of hydrogen metabolism is pivotal to the construction of a framework supportive of a hydrogen-fueled low-carbon economy. Hydrogen metabolism relies on the mechanism of action of hydrogenases.

The Geometry of the Catalytic Active Site in [FeFe]-hydrogenases is Determined by Hydrogen Bonding and Proton Transfer [PDF]

open access: yes, 2019
[FeFe]-hydrogenases are efficient metalloenzymes that catalyze the oxidation and evolution of molecular hydrogen, H2. They serve as a blueprint for the design of synthetic H2-forming catalysts.

Cofactor regeneration by a soluble pyridine nucleotide transhydrogenase for biological production of hydromorphone [PDF]

open access: yes, 2000
We have applied the soluble pyridine nucleotide transhydrogenase of Pseudomonas fluorescens to a cell-free system for the regeneration of the nicotinamide cofactors NAD and NADP in the biological production of the important semisynthetic opiate drug ...

Targeting MYCN in Pediatric and Adult Cancers

open access: yesFrontiers in Oncology, 2021
The deregulation of the MYC family of oncogenes, including c-MYC, MYCN and MYCL occurs in many types of cancers, and is frequently associated with a poor prognosis.

Classical planar algebraic curves realizable by quadratic polynomial differential systems [PDF]

open access: yes, 2017
In this paper we show planar quadratic polynomial differentialsystems exhibiting as solutions some famous planar invariant algebraic curves. Also we put particular attention to the Darboux integrability of these differential systems.The author is ...

Pterin function in bacteria

open access: yesPteridines, 2017
Pterins are widely conserved biomolecules that play essential roles in diverse organisms. First described as enzymatic cofactors in eukaryotic systems, bacterial pterins were discovered in cyanobacteria soon after.

Mechanisms, Cofactors, and Augmenting Factors Involved in Anaphylaxis

open access: yesFrontiers in Immunology, 2017
Anaphylaxis is an acute and life-threatening systemic reaction. Many triggers have been described, including food, drug, and hymenoptera allergens, which are the most frequently involved. The mechanisms described in anaphylactic reactions are complex and

Rabbit PrP Is Partially Resistant to in vitro Aggregation Induced by Different Biological Cofactors

open access: yesFrontiers in Neuroscience, 2021
Prion diseases have been described in humans and other mammals, including sheep, goats, cattle, and deer. Since mice, hamsters, and cats are susceptible to prion infection, they are often used to study the mechanisms of prion infection and conversion ...
