Mechanical coupling in the nitrogenase complex
Fig 9
Correlation patterns of protein dynamics in (A) free MoFe protein and (B) MoFe protein in presence of ATP-bound Fe protein based on HDX measurements recorded after 1h of the deuterium exchange. Red and blue circles correspond to negative and positive correlations, respectively. An empty spot in the matrix (or white circle) signifies lack of any correlation. Size of the circle represents significance of the results: the larger the circle the more significant the correlation. Squares are drawn to highlight clusters with similar correlation patterns.
