Differences in deuterium uptake of the AtPhyB wildtype.
(a) The results for the tongue region of wildtype AtPhyB are mapped to the Pr crystal structure (left) and a Pfr model (right), respectively. The largest changes in deuterium uptake are found for the WGG motif, which has a low exchange rate in Pr compared to a high one in Pfr. (b) A different digestion pattern refers to structural changes in the tongue region. (c) Deuterium uptake difference (Pfr − Pr) near the gap between the GAF-PHY domains. The helical spine as well as a loop and an adjacent beta strand exchanges slower in the Pfr state. PCB = phycocyanobilin.
