Fluorescence-based Monitoring of PAD4 Activity via a Pro-fluorescence Substrate Analog

Abstract:
In Allpyral the alum which has been added to the highly alkaline-pyrididium extract of non-defatted pollen absorbs only 25% of the extracted nitrogenous material, the larger quantity having been discarded with the supernanant. Allpyral contains a relatively small amount of antigenic material compared with conventional aqueous or glycerol preparations. Chemical studies show Allpyral to be a product resulting from an unrealized concept and a faulty method of preparation involving injudicious use of alum.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
