Fungal Laccases and Fumonisin Decontamination in Co-Products of Bioethanol from Maize.

Maize ( L.) may be infected by and , and consequently contaminated with fumonisins (FBs), as well as the co-products of bioethanol intended for animal feed. Laccase enzymes have a wide industrial application such as mycotoxin degradation.

Aflatoxin Decontamination in Maize Steep Liquor Obtained from Bioethanol Production Using Laccases from Species within the Basidiomycota Phylum.

Maize ( L.) is an important crop in Argentina. section can infect this crop at the pre-harvest stage, and the harvested grains can be contaminated with aflatoxins (AFs).

Inhibition of flippase-like activity by tubulin regulates phosphatidylserine exposure in erythrocytes from hypertensive and diabetic patients.

Plasma membrane tubulin is an endogenous regulator of P-ATPases and the unusual accumulation of tubulin in the erythrocyte membrane results in a partial inhibition of some their activities, causing hemorheological disorders like reduced cell deformability and osmotic resistance. These disorders are of particular interest in hypertension and diabetes, where the abnormal increase in membrane tubulin may be related to the disease development. Phosphatidylserine (PS) is more exposed on the membrane of diabetic erythrocytes than in healthy cells.

Activation of H(+)-ATPase by glucose in Saccharomyces cerevisiae involves a membrane serine protease.

Background: Glucose induces H(+)-ATPase activation in Saccharomyces cerevisiae. Our previous study showed that (i) S. cerevisiae plasma membrane H(+)-ATPase forms a complex with acetylated tubulin (AcTub), resulting in inhibition of the enzyme activity; (ii) exogenous glucose addition results in the dissociation of the complex and recovery of the enzyme activity.
