Comparative Genome Assessment of the Two Novel Poly-γ-Glutamic Acid Producing Bacillus Strains

Journal of Pure and Applied Microbiology, 2019
Poly-γ-glutamic acid (PGA) is a homopolyamide, biosynthesized mostly by Bacillus sp. Our study focuses on understanding the genetic differences between the two species of Bacillus for their capability to produce PGA.

Complexation and conformation of lead ion with poly-γ-glutamic acid in soluble state.

PLoS ONE, 2019
Complexation of microbial polymer in soluble state could impact the solubility, mobility, and bioavailability of heavy metals in the environment. The complexation of a bacterial exopolymer, poly-γ-glutamic acid (γ-PGA), with Pb2+ was studied using the ...

Dendrimer pszeudofázisok fizikai kémiai tanulmányozása: dendrimerek módosítása, oldategyensúlyainak, szerkezetének és dinamikájának vizsgálata = Physico-chemical study of dendrimer pseudo phases: functionalization, solution structure, dynamics and equilibria [PDF]

, 2010
Dendrimerek szintézise és analitikája. Amerikai partnerünkkel közösen megállapítottuk, hogy a PAMAM dendrimereknél "váz deviancia" öröklődik a funkcionalizálódás során, míg a "szubsztitúciós diverzitás" természetesen előállításkor keletkezik ...

Osmotic pressure induced coupling between cooperativity and stability of a helix-coil transition

, 2012
Most helix-coil transition theories can be characterized by a set of three parameters: energetic, describing the (free) energy cost of forming a helical state in one repeating unit; entropic, accounting for the decrease of entropy due to the helical ...

Depletion of Branched-Chain Aminotransferase 2 (BCAT2) Enzyme Impairs Myoblast 3 Survival and Myotube Formation [PDF]

, 2019
Much is known about the positive effects of branched-chain amino acids (BCAA) in regulating muscle protein metabolism. Comparatively much less is known about the effects of these amino acids and their metabolites in regulating myotube formation.
