Degradation activity

Substantial amounts of polymalatase have been isolated from plasmodial extracts. This may refer to stored enzyme before secretion, because /3-poly(L-malate) is not degraded in plasmodia [24]. Several other fungi were found to secrete /3-poly(L-malate) degrading activities to L-malic acid (Ratberger, Molitoris and Holler, unpublished results). These enzymes have not yet been purified and characterized.

The fate of xenobiotics in many environments is therefore significantly determined by the degradative activity of anaerobic bacteria.

Many contaminated sites are located in areas with temperatures considerably less than 15°C, and investigations into the role of temperature have therefore been carried out. Some of the cardinal results have been discussed in Chapter 4, and it may be concluded that although the rates at 4-5°C may be low, selection of organisms for adaptation to the ambient temperature will generally ensure that degradative activity is retained. There may, however, be selective degradation of specific groups of components in mixtures such as PCBs.

There are various inhibitors within the coagulation system that counterregulate activation of the coagulation cascade. Among them, antithrombin III (AT-III) and protein C (PC) are the most important (SI). AT-III binds in the presence of heparin the activated factors F-IXa, F-Xa, and F-IIa (thrombin). PC is activated by a complex formed between thrombin and thrombomodulin, a surface protein of endothelial cells. Once activated, PC in the presence of protein S (PS) specifically degrades activated factors F-Va and F-VIIIa. PC decreases in the course of sepsis in relation to the severity of the condition (L15). Experimental studies have... 

The purpose of this paper is to study the role of algae in altering pesticidal chemicals in aquatic environments with special reference to their influence on photochemical degradation activities. 

To study the effect of the protease treatment cell-free suspension, with or without protease treatment, was subjected to gel-filtration chromatography on Sephadex G-75 and the elution patterns were compared (Fig. 1). In each case, two major peaks were detected by monitoring column fractions with absorbance at 280 nm. Degradation activities on mexacarbate, in the presence of FMN and light under anaerobic condition, were measured for each fraction. It was found that the highest activity was associated with peak II. It is interesting to note that protein (s) associated with peak II were detected with or without protease treatment these will be referred to as natural flavoprotein (B, Fig.

The degradation activity depended on the anaerobic conditions and ranged between complete inhibition of biotransformation and mineralization of the herbicide. The degradation and transformation pathways that were observed under different reducing conditions are summarized in Fig. 28.
