Ribonuclease A has been the most studied enzyme of the twentieth century. Work on ribonuclease A has endowed enzymology, as well as protein science, with many paradigms. This work continues to provide a framework for understanding protein structure – function relationships in atomic detail. In addition, knowledge gained by basic research is enabling the rapid deployment of ribonuclease A homolo...

The substitution of gasoline by ethanol with different ratios is commercialized around the world. In this review, an overview on feedstocks, affecting factors, and technical advances in starch production has been systematically presented. Most produced from starchy crops, among which corn, wheat, sorghum are major contributors. Additional crops have also studied for but not yet industrialized. ...

Objective(s): Streptococcus pyogenes produces extracellular hyaluronidase enzyme. This enzyme is directly associated with the spread of the organism during infection. The objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. Materials and Methods: The enzymatic region of hyaluronidase gene was detecte...

Copoazú is a fruit originated from Colombian Amazon belonging to Theobroma genus, which includes species such as cacao raw material for chocolate. Both presented similar processing stages, with different process parameters due the physical qualities of each fruit. Enzymatic, mechanical, and combined methods pulping copoazú seeds their effect on biochemical dynamics fermentation were evaluated. ...

Objective(s):Hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. In the present study, we evaluated the effect of ethanolic extract of Ensete superbum seeds (ESSE) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. Materials and Methods:Glucose, HbA1c, total protein, albumin, renal function mar...
