Obtenção e caracterização bioquímica de xilanases nativas e recombinante do fungo Leucoagaricus gongylophorus
(Universidade Federal de São Carlos, 2013-08-30)
Xylanases are enzymes which randomly cleave the main chain of xylan, the most abundant non-cellulosic polysaccharide of plants cell wall. Xylanases are commonly produced by a wide range of organisms including bacteria, ...
The implementation of NMR techniques for measuring interactions between small organic molecules/inhibitors and enzyme Acetylcholinesterase: a step towards Alzheimer´s control
(Universidade Federal de São Carlos, 2015-05-21)
The inhibition of the acetylcholinesterase (AChE) might be an excellent therapy in controlling Alzheimer’s disease as stated by the cholinergic hypothesis. In this context, the inhibitors of AChE, are of medical and ...
