Currently no effective treatment is available to combat infections caused by Corynebacterium pseudotuberculosis in livestock. Survival of this Gram-positive bacterium in rapidly-growing pathogens in hostile environments ...

The frequency of adenine mononucleotides (A), dinucleotides (AA) and clusters, and the positions of clusters, were studied in 502 molecules of the 5S rRNA.All frequencies were reduced in the evolutive lines of vertebrates, ...

The presence of nucleobases in carbonaceous meteorites on Earth is an indication of the existence of this class of molecules in outer space. However, space is permeated by ionizing radiation, which can have damaging effects ...

A theoretical study of the intermolecular double proton transfer in the adenine-uracil base pair has been performed to model the double proton transfer in the adenine-thymine dimer. The mechanism is analyzed in terms of ...

This work reports the synthesis and characterization of single-walled carbon nanotubes (SWCNT) covalently functionalized with l-lysine (Lys) and the analytical performance of glassy carbon electrodes (GCE) modified with a ...

Adenine phosphoribosyltransferase (APRT) is an important enzyme component of the purine recycling pathway. Parasitic protozoa of the order Kinetoplastida are unable to synthesize purines de novo and use the salvage pathway ...
