1. The types оf pоwer used depend оn the tаsks аnd functions of the pаrticular unit.
This is the reference tо аn аrticle thаt appeared recently in the jоurnal Nature abоut a protein secreted by pathogenic bacteria that cause brown spot in beans, bacterial spec in tomatoes and fire blight in fruit trees. These bacteria infect plant cells, causing them to "drain" cell material leading to cell death. Because of the economic impact of this infection, groups have worked for years to elucidate the mechanism by which this protein infects plant cells. The Nature article reports that alpha fold in combination with cryo EM produced a protein structure that led to the solution of this 30 year old puzzle. Below is a portion of the text from the article along with one of the figure depicting the structure of the protein. Based upon the structural information in the text and the figure, suggest a possible way this protein could “drain” a plant cell such that, cell death results. Image Description AlphaFold2 analysis and cryo-EM imagingTo gain functional insights into the AvrE family of bacterial effectors, we constructed their three-dimensional models predicted by AlphaFold226 using the fast homology search of MMseqs2 (ColabFold) 27. The predicted AlphaFold2 models of DspE from E. amylovora, DspE from P. carotovorum, AvrE from P. syringae pv. tomato (Pst) DC3000 and WtsE from P. stewartii (Fig. 1 and Extended Data Figs. 1 and 2) all reveal an overall similar architecture resembling a mushroom, with a prominent central ẞ-barrel forming the stem, which is surrounded by a globular amino-terminal domain (E. amylovora DspE: K298-H672), a WD40 repeat domain (H673-P912) and two perpendicularly arranged helix bundles (E998-T1222 and A1567-H1647) on the top. The predicted domain arrangement is supported by our cryo- EM imaging of E. amylovora DspE, for which the two-dimensional class averages clearly reveal an overall similar top view to that of the AlphaFold model, with circularly arranged globular domains surrounding a central pore (Fig. 1a,b). Image Description Fig. 1: Model and cryo-EM images of E. amylovora DspE. (a) Three-dimensional model generated by AlphaFold2 using MMseqs2 (ColabFold). DspE (residues 298–1838) is shown in a rainbow color gradient, with the N terminus in blue and the C terminus in red. (b) Cryo-EM two-dimensional class averages of DspE, revealing a circular arrangement of domains around a pore. Scale bars, 5 nm. (c) Surface representation of DspE. (d) Sliced view of DspE. In (c, d), residues are colored based on hydrophobicity. of their hydrophobicity.
