Temporal separation of protein toxin translocation from processing events.

The Purification and Concentration of Diphtheria Toxin: III. Separation of Toxin from Bacterial Protein.

Diphtheria toxin purified by a variety of methods has always contained bacterial protein. This raises the question whether the predominant protein in purified preparations is a fragment of the bacterial protoplasm which carries the toxin, or is itself the toxin. In a previous paper (Eaton, 1936b) it was shown that in various purified preparations there is no relation between the titer of bacter...

Temporal processing of news : annotation of temporal expressions, verbal events and temporal relations

The ability to capture the temporal dimension of a natural language text is essential to many natural language processing applications, such as Question Answering, Automatic Summarisation, and Information Retrieval. Temporal processing is a field of Computational Linguistics which aims to access this dimension and derive a precise temporal representation of a natural language text by extracting...

Processing Optimization of Production of Hydrolyzed Protein from Orange Seed Waste with Pepsin Enzyme

Background and Objectives: The results of observations and studies over the years have shown that health and nutrition are highly related with each other. Bioactive peptides are defined as hydrolyzed proteins, which have the ability to stimulate the desired activities. In this study, the effect of adding pepsin enzyme on orange seed protein was investigated to obtain the hydrolyzed protein, and...

Translocation-specific conformation of adenylate cyclase toxin from Bordetella pertussis inhibits toxin-mediated hemolysis.

Bordetella pertussis adenylate cyclase (AC) toxin belongs to the RTX family of toxins but is the only member with a known catalytic domain. The principal pathophysiologic function of AC toxin appears to be rapid production of intracellular cyclic AMP (cAMP) by insertion of its catalytic domain into target cells (referred to as intoxication). Relative to other RTX toxins, AC toxin is weakly hemo...
