引用 | ジャーナル: Life Sci Alliance / 年: 2024タイトル: Cryo-EM reveals a phosphorylated R-domain envelops the NBD1 catalytic domain in an ABC transporter. 著者: Rodolpho Souza Amado de Carvalho / Md Shamiul Islam Rasel / Nitesh K Khandelwal / Thomas M Tomasiak / ![]() 要旨: Many ATP-binding cassette transporters are regulated by phosphorylation on long and disordered loops which presents a challenge to visualize with structural methods. We have trapped an activated ...Many ATP-binding cassette transporters are regulated by phosphorylation on long and disordered loops which presents a challenge to visualize with structural methods. We have trapped an activated state of the regulatory domain (R-domain) of yeast cadmium factor 1 (Ycf1) by enzymatically enriching the phosphorylated state. A 3.23 Å cryo-EM structure reveals an R-domain structure with four phosphorylated residues and the position for the entire R-domain. The structure reveals key R-domain interactions including a bridging interaction between NBD1 and NBD2 and an interaction with the R-insertion, another regulatory region. We scanned these interactions by systematically replacing segments along the entire R-domain with scrambled combinations of alanine, glycine, and glutamine and probing function under cellular conditions that require the Ycf1 function. We find a close match with these interactions and interacting regions on our R-domain structure that points to the importance of most well-structured segments for function. We propose a model where the R-domain stabilizes a transport-competent state upon phosphorylation by enveloping NBD1 entirely. | |||||||||

Grids were place inside of a Leica EM GP2 equilibrated at 10 degress Celcius amd 80% humidity. Following 10 seconds incubation, the side of the grid to which the sample was applied was blotted on a Whatman 1 paper (3.5 seconds) then immediately plunge frrozen in liquid ethan equilibrated at -185 degree Celcius. |
