| an ice nucleation protein from fusarium acuminatum: cloning, expression, biochemical characterization and computational modeling. | ice nucleation proteins (inp) are a major cause of frost damage in plants and crops. here, an inp gene from fusarium acuminatum was optimized, synthesized, expressed in e.coli and subsequently purified and characterized. the protein belongs to the second class of ice nucleation proteins with an optimum ph 5.5, relative activity and stability between ph 5 and 9.5 and up to 45 °c. the protein was fully active and stable in the presence of dimethyl sulfoxide (dmso), dioxane, acetone and ethyl aceta ... | 2014 | 24930104 |
| role of pyruvate and ascorbate production in regulation of antioxidant enzymes and membrane lpo levels in fusarium acuminatum. | the role of pyruvate and ascorbate in the regulation of superoxide dismutase (sod); catalase (cat); glutathione peroxidase enzymes; and, therefore, membrane lipid peroxidation (lpo) levels in fusarium acuminatum was investigated in media containing either glycerin or glucose as a carbon source, depending on the incubation period, in the range of 5-25 g/l. increasing sod activity between d 9 and 16 of the incubation period showed a positive correlation with a significant increase in pyruvate prod ... | 2005 | 15640554 |
