| Method |
"ATP Hydrolysis Assay—Membrane vesicles and PLS were prepared
as described earlier (ref 6), from strain TA1889 unless specified differently." |
| Comments |
"Purified
HisQMP2 hydrolyzes ATP with a Vmax of 2100 nmol/min/mg of
protein (Fig. 4), which is calculated to correspond to a turnover
rate of 8 s^-1 in the presence of saturating liganded HisJ." |
