Ultrathin films of cellulose were functionalized with iron protoporphyrin IX (FePP). Spin-coating allows the production of silylated cellulose films in a controlled way. Cellulose regeneration is achieved through the hydrolyzation of the silane groups, exposing the film to acidic vapors. To enhance the reactivity of the cellulose surface to the protoporphyrin, carbonyldiimidazole (CDI) was used...

Calmodulin (CaM) is a ubiquitous intracellular protein that regulates biological activities of numerous enzymes and ion channels. Upon responding Ca concentration change, Cadependent CaM activates the hydrolyzation of cGMP by PDE and Ca releasing channel activity of ryanodine receptor. In this dissertation, a series of CaM variants were engineered to enhance Ca binding affinities by increasing ...

This work was aimed to study the preparation and hydrolyzation of cartilage from duck trachea to obtain crude chondrotin sulfate(CS). Duck trachea is comprised of 66.19 ± 0.96% protein and 3.46 ± 0.15% CS (dry basis). HPLC chromatograms revealed that CS of duck trachea contained higher content of ΔDi-4S than ΔDi-6S with trace amount of ΔDi-diSs. To obtain cartilage part of the trachea, use of a...

Ghrelin coded by the GHRL gene is related to weight-gain, its deactivation possibly depending on its hydrolyzation by butyrylcholinesterase (BChE) encoded by the BCHE gene, an enzyme already associated with the body mass index (BMI). The aim was to search for relationships between SNPs of the GHRL and BCHE genes with BChE activity, BMI and obesity in 144 obese and 153 nonobese Euro-Brazilian ma...

Proteins produced by the large and diverse chitinase gene family are involved in the hydrolyzation of glycosidic bonds in chitin, a polymer of N-acetylglucosamines. In flowering plants, class I chitinases are important pathogenesis-related proteins, functioning in the determent of herbivory and pathogen attack by acting on insect exoskeletons and fungal cell walls. Within the carnivorous plants...

BACKGROUND Plants and herbivores can evolve beneficial interactions. Growth factors found in animal saliva are probably key factors underlying plant compensatory responses to herbivory. However, there is still a lack of knowledge about how animal saliva interacts with herbivory intensities and how saliva can mobilize photosynthate reserves in damaged plants. METHODOLOGY/PRINCIPAL FINDINGS The...

UNLABELLED As milk represents the main source of nutrition for infants, the question of an effective human milk substitute becomes mandatory when a formula-fed baby is allergic to cows' milk proteins. In this case, formulas containing extensively hydrolysed milk proteins should be preferred, but even such a formula may cause allergic reactions in highly sensitive patients. If there is evidence ...
