p.7445 right column 2nd paragraph:"On the other hand, it is not clear how an assay based on purine ribonucleoside phosphorylase, an enzyme with a turnover number of 40?s^-1 and Km of 26?µM (primary source), can be used to monitor the millisecond timescale release of nanomolar concentrations of Pi and output rates as high as 500–600?s^-1 (ref 28)." |
