The synthesis of glutamic acid from propane
… various means to form their monomers- the amino acids. This process, in fact, takes place during the digestion and ingestion of proteins as food matter. Today, the most important use of the amino acids is as a food. With the scarcity of food so prevalent throughout the world today, it would seem …

Bacterial poly-gamma-Glutamic Acid (y-PGA) - a promising biosorbent of heavy metals
Poly-γ-glutamic acid (γ-PGA) is a biopolymer made up of repeating units of L-glutamic acid, D-glutamic acid or both. γ-PGA is water soluble, non-toxic and biodegradable, and can be used safely in a variety of applications that are increasing rapidly. This study investigated the production of HMW …

Regulation of rod photoreceptor phosphodiesterase (PDE6) by the glutamic acid -rich protein 2 (GARP2)
… the study was to evaluate the importance of the Glutamic Acid-Rich Protein-2 (GARP2) as a PDE6-interacting protein. First, we confirmed earlier observations that GARP2 is a high-affinity PDE6 interacting protein, and is present in amounts sufficient to stoichiometrically bind PDE6. Addition of …

Poly(glutamic acid) promoted assembly of nucleosome cores on the histone gene quintet of psammechinus miliaris
… assembly of nucleosome cores promoted by poly(glutamic acid) has been optimized with respect to rate and yield. This was achieved by paying attention to the purity of the core constituents and in particular by the use of histones in their octameric form. The suitability of a number of octamer …

A study of the platinum (II), palladium (II), and rhodium (III) chelates of aspartic and glutamic acid
… fairly well known that alpha-amino dicarboxylic acids combine quite readily with basic metal ions such as the alkaline earths. The nature of the problem includes the synthesis and characterization of six platinum metal chelates of two alpha-animo dicarboxylic acids, namely aspartic and glutamic …

Bacterial production of poly-γ-glutamic acid and evaluation of its effect on the viability of probiotic microorganisms
Poly-γ-glutamic acid (γ-PGA) is a naturally occurring biopolymer made up of repeating units of glutamic acid and can be potentially used for multiple applications. This study compared the production of γ-PGA by eight bacteria (B. subtilis 23856, B. subtilis 23857, B. subtilis 23858 B. subtilis …

Regulation of the catalytic and allosteric properties of photoreceptor phosphodiesterase (PDE6) by the glutamic acid-rich protein-2 (GARP2)
… thesis is that one PDE6 binding partner, the glutamic acid-rich protein (GARP2), may regulate PDE6 to reduce its "dark noise", enhance its sensitivity and conserve metabolic energy during rod photoresponse saturation.</p><p>The first aim of this research is to better understand the unique …

Selection of bacterial species from wastewater for potential production of poly (γ-glutamic acid): isolation, characterisation and growth kinetics
… such as the production of alcohols, organic acids and polymers. The nutrient loads in municipal wastewaters are dilute, but add up to significant daily loads because of the massive volumes generated in urban populations. The effluent of most wastewater treatment plants in South Africa is …

Towards value from waste: Bioreactor selection for the reduction of nutrient load and production of Poly-y-glutamic acid
… potential for application in a WWBR is poly-ɣ-glutamic acid (ɣ-PGA.) It is a naturally occurring biopolymer with potential for application in medical, food, agricultural, wastewater treatment and cosmetic industries. A known ɣ-PGA-producing Bacillus subtilis strain was isolated (referred to as …

STUDIES ON NATURAL AND EDIBLE BIOPOLYMERS. ISOLATION, CHARACTERIZATION AND CHEMICAL MODIFICATIONS OF POLY(Γ-GLUTAMIC ACID) (Γ-PGA) FROM BACILLUS SUBTILIS
Poly(γ-glutamic acid) (γ-PGA) is a unusual anionic, water-soluble homopolyamide composed of D- and/or L-glutamic acid monomers, connected by amide bonds between α-amino and γ-carboxyl groups, mainly produced by Gram-positive bacteria of the genus Bacillus. γ-PGA is hygroscopic and water-soluble; in …
