Enzymic degradation of heparin.

A sulphamidase and a sulphoesterase were isolated from adapted cells of Flavobacterium heparinum. These enzymes were partially purified from the 'heparinases' present in the bacterial extracts and characterized. The sulphamidase has a high specificity for glucosamine N-sulphate and glucosamine 2,6-disulphate. The activity decreases sharply with increasing molecular weight ofthe substrates teste...

The enzymic degradation of laminarin. 2. The multicomponent nature of fungal laminarinases.

The enzymic degradation of laminarin. 1. The distribution of laminarinase among micro-organisms.

P-Glucans occur in micro-organisms and higher plants as structural constituents of cell walls, as reserve materials and as extracellular substances of uncertain significance. Laninarin is such a reserve polysaccharide in many Phaeophyceae and it can be regarded as a mannitol-containing fl-D-glucan in which the main polymeric linkage is fl-(1-+3). Enzymes hydrolysing fi-D-(1-+3)-glucans have bee...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
