Amino acid (sequence) defines the folds. And really? Just any random sequence gets you a new fold. I mean, it won't be very useful if you pick a random one, but it'll work and be a new one. I think this is just an artifact of natural selection basing new proteins on existing ones, not an actual useful ("rational" if you can call natural selection rational) selection limit. I don't think that if you designed proteins…

A random sequence may not fold at all! I seem to remember a paper that tried this, creating a bunch of random proteins, and checking how much structure they had - I think they were helical bundles, but don't quote me. The nice thing about stable folds, is that 'nearby' sequences in sequence space - as in, point mutations - are the same fold. If each sequence had a completely different fold, then mutation would be muc…

This reminds me of structural studies in proteins encoded by de novo genes in eukaryotes. They are usually either intrinsically disordered or adopt a molten-globule-like state.

Can we please retire the headline trend of "The Unreasonable ___ of ____ "

At some point someone will analyze this pattern and post an article named "The Unreasonable effectiveness of the 'The Unreasonable X of Y' template".

Everything old is new again! We've had "Go To Statement Considered Harmful" Considered Harmful [1].

Now it's the Unreasonable Effectiveness of "The Unreasonable Effectiveness of X".

It seems like "X is All You Need" is All You Need.

Yes, I was watching a video about that the other day - the 'dark proteome' or the 'ghost proteome' or similar.

All you need is the unreasonable effectiveness of ... Symmetry.

Heh, on my watchlist - ""The Unreasonable Effectiveness of Group Theory" - https://www.youtube.com/watch?v=1XsXRUsNEC4
