wild-type
P. migulae 8R6
and its
ACC deaminase
deficient
mutant
had
activity
levels
of 10.9 and
0.03 mmol mg1 h1,
respectively (Table S1)
The apparent
residual
enzyme
activity
in the two mutants
(in both cases approx. 1% of the wild-type value)
is deemed
to be insignificant
and is within the
margin
of error
of this assay
