Biological context of Potaba

 

Anatomical context of Potaba

  • Incubation of liver cytosol from mutant A and B6.A mice at 37 degrees C for 6 hr resulted in virtual cessation of p-aminobenzoate N-acetylation activity, whereas the steady-state level of immunoreactive NAT2 remained unchanged [18].
  • Culturing HL-60 cells in the presence of p-aminobenzoate, a competitive inhibitor of polyprenyl-4-hydroxybenzoate transferase (Coq2p), produced a significant decrease of CoQ(10) levels without affecting cell viability [19].
 

Associations of Potaba with other chemical compounds

  • In some micro-organisms, p-aminobenzoate synthase and anthranilate synthase share a common glutamine amidotransferase subunit [3].
  • For p-aminobenzoate, its three most intense Raman features, due to a phenyl mode (1607 cm-1) and carboxylate stretching (1383 cm-1) and scissoring (863 cm-1) motions, are little perturbed upon binding and show no changes in the pH range 6.5-8 [20].
  • The strategy included releasing the oligosaccharides by digestion of the purified glycoprotein with endoglycosidase H, separating the released oligosaccharides by high resolution gel filtration, and derivatizing the resulting reducing termini with the uv-absorbing moiety, ethyl p-aminobenzoate [21].
  • Homology of pyridoxal-5'-phosphate-dependent aminotransferases with the cobC (cobalamin synthesis), nifS (nitrogen fixation), pabC (p-aminobenzoate synthesis) and malY (abolishing endogenous induction of the maltose system) gene products [22].
  • Equilibrium solubilities of the first four homologous alkyl p-aminobenzoate esters were determined in methanol, ethanol, and 1-propanol at 25, 33, and 40 degrees; the esters and the alcohols comprise separate homologous series [23].
