THE REUTILIZATION OF NUCLEIC ACID CATABOLITES

In vitro and in vivo inhibition of catalase by uric acid and other nucleic acid catabolites.

Early in this century it was observed that aqueous extracts of animal tissues were capable of inhibiting the activity of catalase in vitro (~). More recently it has been found that either normal adult or growing tissues are very rich in catalase-inhibitory substances (1, 7). I n vivo experiments showed tha t the catalase activity of the liver of rats and mice bearing tumors was 50 per cent of t...

The nucleic acid of African Horse-Sickness Virus

A complex of iron and nucleic acid catabolites is a signal that triggers differentiation in a freshwater protozoan.

The polymorphic ciliated protozoan Tetrahymena vorax can undergo differentiation from the microstomal form, which normally feeds on bacteria and other particulate matter, into the macrostomal cell type, which is capable of ingesting prey ciliates. The process is triggered by exposure of the microstome to an inducer contained in stomatin, an exudate of the prey. To establish the identity of the ...

The Nucleic Acid Database: A resource for nucleic acid science.

The Nucleic Acid Database (NDB) distributes information about nucleic acid-containing structures. Here the information content of the database as well as the query capabilities are described. A summary of how the technology developed by this project has been used to develop other macromolecular databases is given.
