BACKGROUND Metabolic pathway manipulation for improving the properties and the productivity of microorganisms is becoming a well established concept. For the production of important metabolites, but also for a better understanding of the fundamentals of cell biology, detailed studies are required. In this work we analysed the lactate production from(More)
Computational approaches based on Molecular Dynamics simulations, Quantum Mechanical methods and 3D Quantitative Structure-Activity Relationships were employed by computational chemistry groups at the University of Milano-Bicocca to study biological processes at the molecular level. The paper reports the methodologies adopted and the results obtained on(More)
According to different studies, the interaction between amyloid β-peptide (Aβ) and copper ions could yield radical oxygen species production, in particular the highly toxic hydroxyl radical OH· that is suspected to contribute to Alzheimer’s disease pathogenesis. Despite intensive experimental and computational studies, the nature of the interaction between(More)
Amavadin is an unusual octa-coordinated V(IV) complex isolated from Amanita muscaria mushrooms. The outer-sphere catalytic properties of such a complex toward several oxidation reactions are well known. Nevertheless, a remarkable example exists, in which the V(V) (d(0)) oxidized form of amavadin is able to electro-catalyze the oxidation of some thiols to(More)
Bromoperoxidase catalytic activity exerted by oxidated amavadin [V(HIDPA)2](-) (HIDPA = 2,2'-(hydroxyimino) dipropionate) in mono- and bis-protonated forms has been investigated by DFT. Possible reaction pathways for formation of peroxido/hydroperoxido complexes and subsequent bromide oxidation have been systematically dissected. The effect of increasing(More)
