enzymes, effectors, biological activityIntroduction: The fungal and bacterial materials are very useful for testing the influence of low and very low doses of low molecular phenolic effectors on enzymatic system of phenoloxidases when they are incubated together in the reaction space. Aim: Searching ...

Activity was retained when cell integrity was maintained at pH 5.0–6.5 and at salinities of 5 g 100 mL 1. Aminotransferase activity in lysates of two Lb. paracasei strains was maximal at, or close to, pH 6.0 and 30°C but was detectable under simulated cheese conditions. The activity ...
THE procedures for the estimation of enzymes of the urea cycle reported by Brown and Cohen1 have made it possible to study quantitatively the effect of hormones on the individual reactions of the urea cycle. These authors have recently shown that, in rat
Why do enzymes become inactive at very high temperatures? An enzyme has an optimum pH of 7.4. What is most likely to happen to the activity of the enzyme if the pH drops to 6.3? Explain. An enzyme has an optimum pH of 7.2. What is most likely to happen to the activity of the enzy...
In this lesson you will learn about a mixture of enzymes found in pineapples called Bromelain, its sources, therapeutic findings, structure and interactions. Related to this Question What factors affect enzyme activity? Does oxygen affect the activity of the enzyme bromelain?
DEPENDENCE OF THE ENZYME ACTIVITY OF CATALASE ON THE STARCH CONTENT IN RUDERAL VEGETATION OF LANDFILS Introduction. Catalase is concentrated in plant tissues. It is one of the most active enzymes. This enzyme was identified in microbodies (peroxisomes) invo... V Popovych - 《Bulletin of LVIV ...
We recently showed that melatonin counteracted mitochondrial oxidative stress and increased the activity of the mitochondrial oxidative phosphorylation (OXPHOS) enzymes both in vivo and in vitro. To further clarify these effects, we studied here the activity of OXPHOS enzymes and the synthesis of ATP ...
