LITERATURE
IMAGE
bacteriohemerythrin
-
enhances enzyme activity. The maximum activity is observed at a enzyme to bacteriohemerythrin concentration ratio of 4:1
-
catalase
-
increases pMMO activity, catalyzes decomposition of H2O2, on pMMO activity
-
Cu2+
-
pMMO, optimal at 0.3 mM
Fe3+
-
pMMO, optimal at 5.0 mM
lauryl maltoside
-
the stimulatory effect of lauryl maltoside is responsible for the initial increase in duroquinol-dependent activity of the pellet, but no activity with NADH is observed after this solubilization
methanobactin-Cu2+ complex
-
stimulation by methanobactin-Cu2+ complex, no activation in absence of copper, methanobactin is isolated from Methylosinus trichosporium strain OB3b
-
NDH-2
type 2 NADH:quinone oxidoreductase (NDH-2) is required for activity with reductants NADH or quinol as cofactors, overview
