MT consumption by whole cells and lysates of R. pomeroyi DSS-3 wild type and mtoX^- strains (n=3). MT consumption is expressed as nmol MT removed·min^-1·mg protein^-1

Sample	MT consumption (nmol MT min-1·mg protein-1)
Whole cell assays with 0.5mM MT
Wild type	23.4 ± 1.2
mto X-	1.7 ± 1.4
Cell lysate assays with 0.25 mM MT from cells preincubated in the presence (0.5 mM, +MT) or absence of MT (-MT)
Wild type -MT	39.2 ± 14.4
Wild type +MT	139.2 ± 25.5
mto X- -MT	no MT degradation
mto X- +MT	no MT degradation
