Poly-gamma-glutamic acid (γ-PGA) is a widely studied extracellular polymeric substance from Bacillus species. The function of γ-PGA varies with its molecular weight (Mw). Results: Herein, different endogenous promoters in Bacillus licheniformis were selected to regulate the expression levels of ...
Poly(纬-glutamic acid) (PGA) is a biopolymer produced byspp. via the 纬-amide linkages of- and/or-glutamate. Although high-molecular-weight (HMW) PGA possesses many attractive properties, such as flocculating, wound healing, and immune-stimulating effects, no studies have reported factors ...
The structural diversity of extracellular polymeric substances produced by microorganisms is attracting particular attention. Poly-gamma-glutamic acid (γ-PGA) is a widely studied extracellular polymeric substance from Bacillus species. The function of
The esterase activity of equine thrombin as measured with TAMe as the substrate was 1.7 ×l0mole/ min/mg of protein, and the Michaelis constant (K) was 2.36×M. The amino acid contents were determined by a common procedure of amino acid analysis. The content of glutamic acid including its...

KCTC 0697BP separated from 'chungkookjang' a traditional Korean fermented soy bean paste and to its poly-gamma-glutamic acid (or poly-gamma-gutamate, η-PGA) an edible, soluble, anionic, and biodegradable high molecular-weight polymer. Bacillus subtilis var. chungkookjang produces an η-PGA ...
The major amino acids are one residue each of aspartic and glutamic acids, proline, hydroxyproline and alanine and two residues of glycine, and the carbohydrates are one residue each of glucose, xylose and hexosamine and two residues of mannose. The sum of the amino acid and carbohydrate ...
Physicochemical characterization revealed that both proteins are different: the membrane fatty acid-binding protein has a molecular weight of 40 kD and a pI of 8.5–9.0, whereas rat mGOT has a molecular weight of 44 kD and a pI of 9.5–10.0. According to this distinct differences, they ...
