1. Purified human liver and small-intestinal alkaline orthophosphatases release inorganic phosphate at appreciable rates from a variety of organic pyrophosphate substrates. 2. The pyrophosphatase action is inhibited by Mg2+ ions at concentrations that activate the hydrolysis of orthophosphate substrates by these enzymes. 3. The results of mixed-substrate experiments, denaturation studies with heat or urea and starch-gel electrophoresis suggest that both orthophosphatase and pyrophosphatase activities are, in each preparation, properties of a single enzyme. 4. Intestinal phosphatase shows greater pyrophosphatase activity relative to orthophosphatase than the liver enzyme.

It has been suggested that information on the phylogenetic relationships of genera and species could be obtained by comparing the amino acid sequence in the homologous proteins of different species. This procedure is extremely difficult and time-consuming.However, a relatively rapid characterization of proteins can be obtained by analysing their mobilities with starch-gel electrophoresis and examination of antigenic diversity by the agar gel diffusion technique of Ouchterlony.

Starch gel electrophoresis was used to fingerprint 55 Taxus plants, listed as 21 species and/or cultivars. Plants were analyzed for six enzymes, representing eight putative loci. Within many of the cultivars, different fingerprints were observed, indicating nomenclatural errors in Taxus.

Procedures are described for separation and purification of electron-dense bodies previously observed in intact endosperm by electron microscopy. Isolated bodies consist largely of protein. By starch-gel electrophoresis, the bodies contain predominantly slow-moving protein components similf1l' to those found in acetic acid extracts of whole endosperm.

The water-soluble esterases of a microsome-free supernatant of the electric tissue of Electrophorus electricus were separated by vertical-zone electrophoresis in starch gel. Specific and nonspecific substrates and inhibitors were used in conjunction with histochemical techniques to identify the enzymes. Acetylcholinesterase was present in the form of four bands of activity, the electrophoretic mobility of which was suggestive of aggregated forms of the enzyme. Pseudocholinesterase was detected as two weak bands of activity. A third esterase was identified as a nonspecific carboxylesterase and shown to be a sialoprotein.
