malfunction
metabolism
physiological function
-
a truncated pyruvate oxidase mutant containing an in-frame fusion of TnphoA to the pyruvate oxidase gene is defective in H2O2 production
malfunction
-
in an enzyme-deficient mutant of Lactobacillus johnsonii NCC 533, oxygen is not able to overcome acetate dependency nor does it relieve the CO2 dependency. The mutant has a lower growth rate, both aerobically and aerobically
malfunction
-
inactivation of pox causes a dramatic reduction in H2O2 production from lactate
malfunction
mutants lacking the enzyme gene are defective in pneumolysin release

C1- and C2-compound production is largely depend on pyruvate oxidase activity
metabolism
-
C1- and C2-compound production is largely depend on pyruvate oxidase activity
-
-
pyruvate oxidase is involved in hydrogen peroxide production
physiological function
-
Pox performs a synergistic action with lactate oxidases in converting lactate into H2O2
physiological function
-
pyruvate oxidase expressed in Chlamydomonas reinhardtii increases oxygen consumption and has potential for improving photosynthetic hydrogen production in Chlamydomonas reinhardtii
physiological function
enzyme expression of enhances pneumolysin-dependent cell death
physiological function
enzyme-mediated H2O2 induces programmed cell death in Streptococcus sanguinis
physiological function
-
the enzyme is required for capsule formation
physiological function
-
Lactobacillus delbrueckii displays strain-specific inhibition of Pseudomonas gingivalis growth in vitro. Purified, catalytically active, recombinant pyruvate oxidase is sufficient to inhibit P. gingivalis growth in vitro without the addition of cofactors
