Km's for Mehler reaction

[feild taylor s]

        Hello!
I am curious to know if any one could direct me to sources or provide me
with Km values oxygen utilization via the Mehler reaction and
mitochondrial respiration.  Any units (micromoles, microbars, %) would be
great.  I found one estimate for the Mehler reaction in chloroplasts
around 1% O2 published by Schreiber.  Is there any variabilty tied to
that number?
