6-Phospholysine phosphatase (30 kDa) and 3-phosphohistidine/6-phospholysine phosphatase (150 kDa) were purified partially from rat brain cytosol. The former hydrolyzed 6-phospholysine to inorganic phosphate and lysine, and the Km value was 0.83 mM. The latter hydrolyzed 6-phospholysine or 3-phosphohistidine to inorganic phosphate and lysine or histidine, and the Km values were 0.78 and 0.37 mM ...
In the presence of inorganic phosphate, uridine 5'-diphosphate glucose (UDPG) is specifically hydrolyzed to glucose 1-phosphate and UDP by a unique enzyme, UDPG phosphorylase. The activity of the enzyme was maximally stimulated by fructose 2,6-bisphosphate, a regulatory metabolite recently discovered in both plants and animals, and by 2-phosphoglyceric acid. At 1 muM, fructose 2,6-bisphosphate ...
Pyruvate kinase of Streptococcus mutans JC 2 had an absolute and specific requirement for glucose-6-phosphate. Inorganic phosphate was a strong inhibitor. The enzyme required K+ or NH4+ and Mg2+ or Mn2+. S. mutans FIL and E 49, Streptococcus bovis ATCC 9809, and Streptococcus salivarius ATCC 13419 had also glucose-6-phosphate-dependent pyruvate kinases, whereas Streptococcus sanguis NCTC 10904 ...
Effect of inorganic phosphate on ferrous ionand ascorbate-induced lipid. peroxidations of isolated rat liver mitochondria was investigated. As a result it has been shown that phosphate accelerates the ferrous ion.induced lipid peroxidation; namely, phos. phate shortens the induction lag period of the lipid peroxidation reaction but the malondialdehyde after onset of its production is yielded at...
