Abstract:

Human angiotensin-converting enzyme (ACE) is a key enzyme in the regulation of blood pressure via the renin-angiotensin and kallikrein-kinin systems. A number of orally active drugs have been developed over the years that target somatic ACE, for the treatment of hypertension, myocardial infarction and congestive heart failure. Protein structural information about ACE is an important key for the understanding of the mechanism and substrate-specificity of the enzyme. However, this information has only begun to be elucidated in the past year, with the solution of crystal structures of human testi

Studies the links between grape composition, wine composition and wine sensory properties. Developed a new method of measuring glycoside concentration in grapes (glycosyl-glucose assay) and a modified measurement of wine colour density in red wine. These were used to analyse samples of Shiraz grapes and wines from a comprehensive vineyard irrigation trial. Glycosyl-glucose concentrations shows promise for the prediction of wine composition and flavor intensity.

Abstract:

The aim of this study has been to explore the site specific phosphorylation pattern of rat heart glycogen synthase paying particular attention to phosphorylations that are important to the in vivo control of enzyme activity. This problem has been approached using techniques of immuneprecipitation of 32P labeled synthase from hormonally responsive, freshly isolated adult rat cardiomyocytes. Identification of the active subunit of rat heart glycogen synthase was accomplished by immuneprecipitating synthase from 32P-labeled cardiomyocytes and performing Western blot analysis on DEAE-cellulose fra

Functional analysis demonstrated that the cellulase, mannanase and xylanase activities of PmGH (130 kDa) were attributed to the GH5 catalytic domain. The presence of the GH6 catalytic domain resulted in slightly increased cellulase activity in PmGH. Optimal PmGH activity and fu

Carbohydrates are one of the most important biochemical molecules due to their role as energetic resource for non-photosynthetic organisms, cell-cell recognition and adhesion, protection of cell membranes of bacteria and plants and ensure the proper functionality of several enzymes. Glycoproteins are important components of cell surfaces and the extracellular medium where molecular-cell interactions take place. Defects in the activity of glycoproteins are the cause of several human diseases, such as diabetes and lysosomal storage diseases. Glycoside hydrolases (GHs) are one of the most releva

This microbe is predicted to possess an array of glycoside hydrolases, majority of which are involved in starch utilization. Presented here is a comparative functional analysis of two alpha-glucosidases, Family 31 Glycoside Hydrolases from Bacteroides thetaiotaomicron. Enzymatic kinetics revealed these enzymes both preferentially cleave alpha-(1,6) linkage in comparison to the predicted alpha-(1,4) and favour maltose derived substrates of longer length.

Abstract:

碩士<br>東海大學<br>食品科學系<br>105<br>Diabetes is associated with deficiencies in insulin secretion or activity. Excess reactive oxygen species are building up with chronic hyperglycemia, and are subsequently contributing to oxidative stress and complications. Antioxidants have important roles in disorders involving oxidative stress. Glycosidases are not only involved in human digestion, but also affect the occurring of many metabolic diseases such as diabetes. The most important glycosidases in human digest system are α-amylase and α-glucosidase. Lonicera japonica Thunb., is an herbaceous plant of Ca
