in order to get a protein to even work as intended it has to be printed off of DNA (LONG STORY) and then typically folded into the correct shape by other proteins if the folding goes badly usually it just doesnt work as an enzyme and gets chopped up
(occasionally for certain enzymes if the folding goes very badly it turns itself into an enzyme whose function is to turn working enzymes into misfolded enzymes and oh shit now you are going to die)https://science.sciencemag.org/content/373/6554/475 …
all of this is to say that the sons of bitches who published this have managed to take an unfathomably complex and incredibly delicate molecular machine developed over god knows how many millions of years such that its orientation is the same in all known life,
and somehow managed to get this entire 3D configuration perfectly inverted to work on DNA that is DNA it just spins the wrong way im in awe
a few end notes the reason they want to make a "DNase" ie an enzyme that chops up DNA is because all of the existing DNases only work on D-DNA and so if they keep making this shit it will be hard to dispose of elegantly I guess?https://twitter.com/eigenrobot/status/1420952819901755393?s=19 …
RNA polymerase is a molecule that goes down a DNA strand and translates the DNA into instructions for making protein. they made a left hand version of this too apparentlypic.twitter.com/IVRzAxYqbf
ribosomes are enormous multi-part protein machines that take RNA and turn it into proteins left is sort of what ours looks like, right is a bacterial version I guess they're making these nextpic.twitter.com/uE9ZMFNsyf
overall I dont know what the fuck is going on but the fact that this is not only possible but an accomplished feat is making me think that molecular biology is way more advanced than is commonly understood and things are gonna get Weird real real fast good luck out there
will try to answer questions, please keep in mind that I was never a great biology student and I haven't studied anything since the mid aughts
"why is this named so and so" biology is a field full of sickos. for example they named a gene that mutates and kills people "Sonic Hedgehog" as a joke and now doctors have to tell moms their kid is dying because of a sonic hedgehog mutationhttps://twitter.com/NLRG_/status/1420965217060655106?s=19 …
they would probably be like us but we couldnt eat them. and vice versa. I mean we could but maybe a bunch of the molecules would be the wrong chirality so we couldnt digest them with our enzymeshttps://twitter.com/edwardW2/status/1420966805955223555?s=19 …
my guess is none although it would be weird if idk some invert engineered autotroph escaped and somehow started competing with R-DNA autotrophs and outcompeted them because nothing would eat them and oh shit now we die I guess?https://twitter.com/__frye/status/1420968621732339715?s=19 …
I dont have the slightest clue maybe? I guess inverted prions would probably be saferhttps://twitter.com/LoneVoltsAhead/status/1420968529843658758?s=19 …
im inclined to extend benefit of the doubt here because theyre claiming (i) to have actually built something that (ii) doesnt contravene laws of physics as they currently exist and (iii) has no obvious political valence but yes who knows it may be trash https://twitter.com/edibleflowerga1/status/1420964967981928448?s=19 …
update probably real https://twitter.com/halvorz/status/1420976494235602947?s=19 …
as far as applications we're like a hop skip and a jump from solving climate change and peak oil in a fell swoop [joke tweet]https://twitter.com/asingleoat/status/1420954835805884416?s=19 …
gonna pat myself on the back for apparently independently deriving a standard view of the ecological dangers of mirror life so yes if mirror cyanobacteria escaped from a lab we would probably all die fortunately biology labs are proven extremely securehttps://twitter.com/prawncis/status/1420982623048925187?s=19 …
an upside of a mirror cyanobacteria escape and population explosion would be that huge quantities of CO2 would be extracted from the atmosphere, solving global warning apart from the mass extinction of R-DNA life there may other minor side effectshttps://en.m.wikipedia.org/wiki/Great_Oxidation_Event …
