increase speed Kinesin/dynein

And talking about molecular motors. Is there a way to increase the flagellar rotation speed? Is is possible to increase the proton concentration by mean of engineering a V-type ATPase in the membrane that pumps in protons at the expanse of ATP? Tnx

Re: 5 best proofs of evolution

... you would recognize them as the product of an intelligent source. No one would expect an outboard motor -- much less one as incredible as the flagellar motor -- to be the product of a chance assemblage of parts. Motors are the product of intelligent design. We are not talking about a"chance ...

Re: 5 best proofs of evolution

... a microscopic dime. It takes only a quarter turn for them to stop, shift directions and start spinning 100,000 rpm in the opposite direction! The flagellar motor has two gears (forward and reverse), is water-cooled, and is hardwired into a signal transduction (sensory mechanism) so that it receives ...

AMPHITRICHOUS MOVEMENT

I can think it's probably by the direction of flagellar spin. Bacteria move by 'spinning' their flagella and thus the arrangement of flagellin helices which construct flagella is in certain direction (either right spin or left spin). So, I can say ...
