To celebrate #DarwinDay on Feb. 12, I'm going to begin rereading the 1st vol. of Janet's Browne's excellent biography, Voyaging, then the 2nd vol., The Power of Place, in anticipation of her releasing an updated, condensed single volume in June.

What’s new?
New1 (eEF3 homolog) stops ribosomes from stalling at C-terminal AAA/AGG/CGU codons. No New1 = collisions + Hel2 recruitment + Cue2-mediated no-go decay.

Does targeting enzymes and substrates in a condensate lead to rate enhancement? No. Here, we investigate how the condensate environment can inhibit an enzyme reaction.
Spoiler: Mass-transport limitations. We find a strong correlation between diffusion and reaction rates.
