Pre-hydrolytic states using the system BmrA-E504A (catalytically inhibited). Percentage of ADP (Δ) and ATP (○) in the presence of the mutant BmrA-E504A (symbol filled in blue) or of the mutant, which does not bind the nucleotide, BmrA-K380A (symbol filled in green). BmrA-K380A was chosen as a negative control in order to exclude the possibility of an ATPase contaminant in the sample (A). 31P 1D CP spectrum of BmrA-E504A:ATP (B). The overly of the alanine region of 13C-13C-DARR spectra of BmrA-E504A (blue) and BmrA-E504A:ATP (red) (C). Results in panels (A) and (B) are original, and spectra in (C) were adapted from Lacabanne et al. 2019 [92] (http://creativecommons.org/licenses/by/4.0/.).
