Japanese cell biologists have uncovered more evidence for supernatural design of proteins inside the cell. They discovered an amazing biochemical machine that facilitates and controls the movement of proteins along microtubules—akin to monorail transportation systems—within the cell. The research team examined one protein moving along a microtubule with high enough resolution to see the individual atoms in the protein molecule. They observed within the protein two loops that encompassed the microtubule. Each loop could be put into a strong gripping mode through the removal of water at the site or into a slipping mode through the addition of water at the site. Through alternating the grip and slip modes of both loops the protein can move along the microtubule in a movement similar to that manifested by an inchworm. The researchers also found two switching devices near the loops that control the timing of the grip and slip modes. The biochemical efficiency is truly remarkable in three ways: 1) energy use, 2) small size of the moving parts, and 3) switching control. The researchers were so impressed that they recommended that the design principles they discovered should be exploited for nanotechnology machines. Such exquisite design attests to a supernatural Designer.
