Digestive activity of lysosomes. I. The digestion of proteins by extracts of rat liver lysosomes.
The hydrolysis of acid-denatured human or bovine globin at 37” by extracts of highly purified rat liver lysosomes was most extensive between pH 4.4 and 5.6. After exhaustive digestion under these conditions, the ninhydrin-positive material released by enzymatic hydrolysis amounted to 70% of that released by acid hydrolysis. The main products of hydrolysis were free amino acids (42% of the total...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولDemonstration of adenosine deaminase activity in human fibroblast lysosomes.
Human fibroblast lysosomes, purified on Percoll density gradients, contain an adenosine deaminase (ADA) activity that accounts for approximately 10% of the total ADA activity in GM0010A human fibroblasts. In assays of lysosomal ADA, the conversion of [3H]adenosine into [3H]inosine was proportional to incubation time and the amount of lysosomal material added to reaction mixtures. Maximal activi...
متن کاملActivity-dependent trafficking of lysosomes in dendrites and dendritic spines
In neurons, lysosomes, which degrade membrane and cytoplasmic components, are thought to primarily reside in somatic and axonal compartments, but there is little understanding of their distribution and function in dendrites. Here, we used conventional and two-photon imaging and electron microscopy to show that lysosomes traffic bidirectionally in dendrites and are present in dendritic spines. W...
