The mechanism of liberation of penicillinase from Bacillus subtilis.
The effects of various factors on the release of penicillinase from apparently undamaged cells of a growing culture of Bacillus subtilis were investigated. The enzyme was not eluted from the cells by treating them with high concentrations of salt. Its liberation did not take place at all a t Oo, and was nearly completely inhibited a t pH values below 6.0, whereas chloramphenicol, at concentrati...
متن کاملThe mechanism of halogen liberation in the polar troposphere
Sudden depletions of tropospheric ozone during spring were reported from the Arctic and also from Antarctic coastal sites. Field studies showed that those depletion events are caused by reactive halogen species, especially bromine compounds. However the source and seasonal variation of reactive halogen species is still not completely un-5 derstood. There are several indications that the halogen...
متن کاملThe mechanism of platelet release.
The mechanism of platelet release has been studied in mouse bone marrow, using scanning and transmission electron microscopy. Cytoplasmic processes extended into sinusoids by megakaryocytes were found to undergo attenuation, and at the distal end develop constrictions between segments of platelet size. Rupture at sites of constriction is thought to release platelets. Microtubules were present i...
متن کاملLiberation of tryptic fragments from caseinomacropeptide of bovine x-casein involved in platelet function
Carbohydrate-free caseinomacropeptide (CMP) was purified from rennet-hydrolysed caseinate by trichloroacetic acid precipitation and DEAE-TSK Fractogel-650 ion-exchange chromatography. To study the liberation of 106-112, 106-116 and 113-116 fragments from carbohydrate-free CMP involved in platelet function, a quantitative study was made on the rate of hydrolysis of the three peptidic bonds that ...
متن کاملRochester Engines of Liberation Engines of Liberation 1
Electricity was born at the dawn of the last century. Households were inundated with a ßood of new consumer durables. What was the impact of this consumer durable goods revolution? It is argued here that the consumer goods revolution was conducive to liberating women from the home. To analyze this hypothesis, a Beckerian model of household production is developed. Households must decide whether...
