Sedolisins (serine-carboxyl peptidases) are proteolytic enzymes whose fold resembles that of subtilisin; however, they are considerably larger, with the mature catalytic domains containing approximately 375 amino acids. The defining features of these enzymes are a unique catalytic triad, Ser-Glu-Asp, as well as the presence of an aspar- tic acid residue in the oxyanion hole. High-resolution crystal structures have now been solved for sedolisin from Pseudomonas sp. 101, as well as for kumamolisin from a thermophilic bacterium, Bacillus novo sp. MN-32. The availability of these crystal structures enabled us to model the structure of mammalian CLN2, an enzyme which, when mutated in humans, leads to a fatal neurodegenerative disease. This review compares the structural and enzymatic properties of this newly defined MEROPS family of peptidases, S53, and introduces their new nomenclature.

W pracy zbadano stopień aktywności enzymów pektynolitycznych, celulolitycznych, amylolitycznych i proteolitycznych, a także zdolność do uruchamiania nierozpuszczalnych fosforanów przez fluoryzujące pałeczki z rodzaju Pseudomonas. Bakterie wyizolowano z ryzoplany lnu włóknistego, uprawianego w systemie zmianowania i monokultury. Żaden z izolatów nie wykazywał aktywności enzymatycznej wobec celulozy, natomiast pozostałe wielocukry hydrolizowane były przez wszystkie izolaty. Bakterie były najbardziej aktywne wobec białka. Oceniono również ich właściwości antagonistyczne względem wybranych patogenów grzybowych wyizolowanych z tego samego środowiska. Wszystkie z nich, chociaż w różnym stopniu, hamowały rozwój grzybów.

Studies performed in a field indicate that podzolic soil combined with sewage sludge under Salix viminalis L. cultivation exhibited an increase in lipolytic bacteria and fungi numbers as well as a clear stimulation of lipase activity at level A. These changes increased in accordance with the increase of sludge concentration in the soil, and remained in the second and the third year of the experiment. However, a decrease of lipase activity was observed in subjects with a higher sludge concentration in the third year. Disturbances of microbial and enzymatic soil properties after the addition of sewage sludge occurred less intensively at the 20-40 cm than the 0-20 cm layer. In general, a slight stimulation of lipolytic bacteria and fungi and a stronger stimulation of lipase activity was found with higher doses of sludge. As at level A, these changes remained active for two years, showing a decline of lipase activity in the third year.
