An oxidase is an enzyme that catalyzes an oxidation-reduction reaction, especially one involving dioxygen (O2) as the electron acceptor. In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H2O) or hydrogen peroxide (H2O2). Some oxidation reactions, such as those involving monoamine oxidase or xanthine oxidase, typically do not involve free molecular oxygen.
The oxidases are a subclass of the oxidoreductases.
An important example is cytochrome c oxidase, the key enzyme that allows the body to employ oxygen in the generation of energy and the final component of the electron transfer chain. Other examples are:
In microbiology, the oxidase test is used as a phenotypic characteristic for the identification of bacterial strains; it determines whether a given bacterium produces cytochrome oxidases (and therefore utilizes oxygen with an electron transfer chain).
In my grave down below
Hell's fire starts to glow
My prayers have now been heard
By my lord, my god. master lucifer
There is no life or birth
When the undead walk the earth
Unholy blaspheme and torment
Are now set free.
Lead us into temptation
A reign of terror will begin
Deliver us to evil
We promise death, world's end
Incubus in the sky
Pentagram held high
Hell's filth hounds begin to bark
The bells begin to tone
Virgin lies in blood
The blood was once her own
The redness and the horror of blood
Swept acro55 the land I stood
Lead us into temptation
A weigh of terror will begin
Deliver us to evil
We promise death, world's end
Black prince of hell
In fire he reigns
Your god above wrapped up in chains
There is no love
When works collide
Deliver us to evil
When god has died
I laugh while they cry
Their fears build up inside
In their confusion they try to run
But it's no use, my work is done
Slow death is the price
For living such wasted lives
Their bodies they burn and bleed
Until they bow, my word they heed
You've led us into temptation
Our reign of terror has begun
Deliver us to evil
Prince of hell
Satan's son
