Full text

Abstract:

The application of MIDA boronates (MIDA = N-methyliminodiacetic acid) in Suzuki- Miyaura reactions has increased over the last years. This is mainly because in many cases, the replacement of the boronic acid for the respective MIDA boronate has a positive result in the reaction yield. The key feature that makes MIDA boronates efficient coupling partners is that they can undergo a slow hydrolysis reaction under Suzuki-Miyaura conditions, which generates the boronic acid in situ. The control of the hydrolysis rate is crucial to keep a low concentration of the boronic acid to avoid some of the si

Abstract:

Phosphotriesterase (PTE) is a zinc metalloenzyme that catalyzes the hydrolysis of organophosphorus compounds. Metal ion roles during binding and catalysis are probed by comparing the kinetic properties of Zn/Zn, Cd/Cd, and Zn/Cd PTE with a variety of phosphate trisesters. The metal in the α-site of the binuclear metal center modulates the pKa values determined from pH-rate profiles. These results suggest that the α-metal is responsible for activating the nucleophilic hydroxide. In an effort to determine the function of the β-metal, the kinetic parameters for diethyl p-chloro

Abstract:

Nitrogenase consists of two metalloproteins, the MoFe protein and the Fe protein. The MoFe protein is an α2β2 heterotetramer and the Fe protein is an α2 homodimer. The catalytic cycle of nitrogenase involves binding of the Fe protein to each αβ catalytic half of the MoFe protein, electron transfer followed by ATP hydrolysis, Pi release and eventually dissociation of the two proteins. This cycle has to be repeated eight consecutive times to reduce one molecule of N2. The two catalytic halves of the MoFe protein had been considered to be independent of each other.

Abstract:

Introduction: The New Delhi metallo-β-lactamase (NDM-1) is an enzyme synthesized by bacterium which hydrolyses β-lactam antibiotics and inhibits their antibiotic effects. Its active site is highly diverse and the hydrolysis mechanism is not yet fully understood. So, there is currently no clinically useful inhibitor for this enzyme. Due to this β-lactam resistant characteristics and the ease of horizontal gene transfer between bacteria, NDM-1 producing bacteria poses a great threat to public health. Objective: Structural analysis on Zn-Zn distance in the active site of NDM-1 was carried out

Abstract:

The exoglucanase from Cellulomonas fimi catalyses the hydrolysis of cellobiose units from the non-reducing terminus of cello-oligosaccharides with overall retention of anomeric configuration. Its mechanism of action is therefore thought to involve a double displacement reaction, involving as the first step, formation of a glycosyl-enzyme intermediate (glycosylation) and as a second step, the hydrolysis of this intermediate (deglycosylation). This mechanism is investigated here through the study of the kinetics of hydrolysis of aryl β-glucosides and aryl β-cellobiosides and by employing the mec

Abstract:

The chemical mechanisms of glycoside hydrolases, which catalyze the hydrolysis of glycosidic linkages, are some of the most extensively studied amongst enzymatic reactions. Decades of research have led to the widespread acceptance of the two general glycosidase mechanisms--both involving nucleophilic displacement steps and oxocarbenium ion-like transition states--first proposed by Koshland in 1953. Glycoside hydrolase family 4 is an anomaly within this large class of enzymes. Not only does this family uniquely contain both α- and β-glycosidases, but members of family 4 also require both a diva

Most recently, studies in this lab have emphasized the idea that the biophysical state of the bilayer (in terms of lipid order, spacing, and fluidity) is relevant in determining the probability of one phospholipid escaping the membrane to be hydrolyzed.

Abstract:

Tese de Doutoramento em Ciências Veterinárias<br>Xyloglucan (XG) is the major plant cell wall hemicellulose. Biochemical and structural studies on a xyloglucanase, Xgh74A, from Clostridium thermocellum are presented here. In addition, the carbohydrate-binding modules (CBMs) from C. thermocellum Cel9D-Cel44A, CtCBM30 and CtCBM44, which recognize XG, are characterized in this work. CtCel9D-Cel44A’s C-terminal module of unknown function is a CBM, constituting the founder member of family 44. Structural studies revealed that both CtCBM30 and CtCBM44 present Type B binding site topologies whe

Abstract:

A series of lab-scaled digestion studies including conventional mesophilic anaerobic digestion(MAD), thermophilic anaerobic digestion (TAD) at a range of treatment temperatures, and mesophilic high solids digestion of thermally pretreated wastewater sludge (THD) were carried out. Enhanced digestion performance in terms of solids destruction and methane generation by THD relative to MAD was achieved, and was largely attributable to the solubilization and subsequent biodegradation of energy-rich substrates within blended primary and secondary sludge. TAD was observed to underperform MAD, especia

Abstract:

Anaerobic digestion has been the preferred method for reducing and stabilizing waste sludge from biological wastewater treatment for over a century; however, as sludge volumes and disposal costs increase, there has been a desire to develop various methods for reducing the volume of sludge to be treated, improving the performance of the digesters, and increasing the energy value of the sludge. To this end, there have been numerous pretreatment and side-stream systems studied and developed over the past several decades with the overall goal of reducing the volume of biosolids to be disposed of
