An early event that occurs in response to alcohol consumption is mitochondrial dysfunction, which is evident in changes to the mitochondrial proteome, respiration defects, and mtDNA damage. S-Adenosylmethionine (SAM) has emerged as a potential therapeutic for treating alcoholic liver disease through mechanisms that appear to involve decreases in oxidative stress and pro-inflammatory cytokine pr...
A Cl- and NO3- insensitive oxalate oxidase, purified from the roots of 10-day old seedlings of grain Sorghum has been immobilized on polyvinyl alcohol (PVA) membrane through entrapment with 96.07% retention of initial activity. The membrane bound enzyme showed an increase in optimum pH (from 5.0 to 6.5), time of incubation (from 5 to 10 min) and Km for oxalate (from 0.38 to 6.23 mM), but decrea...
Vanillyl-alcohol oxidase (VAO) from Penicillium simplicissimum is an inducible flavoprotein involved in the biodegradation of lignin-derived aromatic compounds. The enzyme is the prototype of a newly recognized family of structurally related oxidoreductases, whose members share a conserved FAD-binding domain. The flavin cofactor in VAO is covalently linked to His422 of the cap domain. This cova...
Vanillyl-alcohol oxidase (VAO; EC 1.1.3.38) contains a covalently 8alpha-histidyl bound FAD, which represents the most frequently encountered covalent flavin-protein linkage. To elucidate the mechanism by which VAO covalently incorporates the FAD cofactor, apo VAO was produced by using a riboflavin auxotrophic Escherichia coli strain. Incubation of apo VAO with FAD resulted in full restoration ...
Platelet monoamine oxidase B (MAO-B) has been proposed to be a biological marker for the properties of monoamine systems, with low activity being associated with vulnerability for high scores on personality traits such as sensation seeking, monotony avoidance, and impulsiveness, as well as for vulnerability for alcoholism. In the present study, platelet MAO-B activity was analysed in 78 rhesus ...
Similar to effects of alcohol on the heart, liver, and brain, the effects of ethanol (EtOH) on lung injury are preventable. Unlike other vital organ systems, however, the lethal effects of alcohol on the lung are underappreciated, perhaps because there are no signs of overt pulmonary disorder until a secondary insult, such as a bacterial infection or injury, occurs in the lung. This paper provi...
