Biocompatible graft copolymers from bacterial poly(γ-glutamic acid) and poly(lactic are realized using a “grafting to” approach combined with click chemistry.

A cell envelope particulate fraction from an encapsulated strain of Bacillus licheniformis ATCC 9945A contains a polygldamyl synthetase which catalyzes the polymerization of L-glutamic acid to form a high molecular weight polymer of y-D-glutamic acid. The reaction, which is specific for L-glutamic acid, requires ATP and Mg2f ion and is stimulated by K+ ion and dithiothreitol. A nearly Z-fold in...

Clove oil is used in fish anesthesia and expected to have a mechanism via glutamic receptor. The present study explores the activities of clove oil and its major compound, eugenol, in comparison with L-glutamic acid on glutamic receptor of silkworm muscle and fish anesthesia. It was found that clove oil and eugenol had similar effects to L-glutamic acid on inhibition of silkworm muscle contract...

The metabolism of glutamic acid in the animal body and in a number of microorganisms has been studied estensively in recent years, but there are few records of its behavior when administered to higher plants. Naylor and Tolbert (1) cultured seedling leaves of barley (Ziordeum vulgare) on solutions of glutamic acidCl4 for periods up to 3 hours and examined extracts of the tissues by paper chroma...

(1) In order to study the relationship between the energy metabolism via TCA cycle and amino acid metabolism as well as protein synthesis, C14-labelled substrates were used for tracer experiment . (2) Considerable C14O2 formation was noted from carbohydrates such as acetate-1-C14, pyruvate-1-C14, and pyruvate-3-C14, while a smaller amount of C14O2 was produced from amino acids such as glycine1-...
