Inorganic phosphate producing activities (in nmol released per minute per mg protein) of isolate protein extracts when given substrates for PhnA (phosphonoacetic acid, grey bars), PhnX (phosphonoacetaldehyde, chequered bars) or PhnZ (1-hydroxy-2-aminoethylphosphonic acid, white bars) enzymes. Data are averages of biological triplicates; error bars show standard error of the mean
