Estas últimas se sintetizan a partir de unidades de acetato para formar un policétido lineal dimetilado, que se condensa con el aminoácido L-alanina, seguido de hasta cinco reacciones de oxigenación y dos esterificaciones. El primer paso es catalizado por una policétido sintasa (...
sphaericus es incapaz de utilizar hexosas o pentosas como fuentes de carbono, aunque puede utilizar el aminoazúcar N-acetilglucosamina (GlcNAc), monómero de la quitina, entre otros polisacáridos. Para su utilización, posee un transportador PTS activo (sistema de fosfotransferasa dependiente...
For the H7 atom, the inductive effect exerted by the hydrogen of the amino group of the indole ring is presumably marked, which is evident as an exchangeable proton, given that its signal in the 1H NMR spectrum is not evident or appears enormously broadened. Thus, the electronic density of...

When pro- ceeding from the enol isomers to keto forms, the labile proton-transfer from the exo OH group to the endo C atom decreases not only the stability of the keto isomers but also electron delocalization (measured by HOMED). The highest HOMED variations occur for the five- and ...
The syn-B vectors have also been shortened to less than 10 amino acids for optimizing their translocation properties. The families of these peptides have been used for brain delivery of poorly brain-penetrating drugs. For example, L-SynB1, L-SynB3 and D-SynB3 significantly increase the brain...
In comparison to protein S-sulfhydration, nitric oxide-mediated protein S-nitrosylation has been extensively investigated, including its formation, regulation, transfer and metabolism. Although the investigation on the regulatory mechanisms associated with protein S-sulfhydration is still in its infancy, ...
