Flow matching and diffusion perform comparably on biomolecular structure prediction^[1]. This is, to my knowledge, the only head-to-head comparison of these two approaches for protein structure modeling or design.

Not all high-fitness sequences have plausible evolutionary paths from lower-fitness starting points via sequential introduction of mutations

I first saw this precise idea articulated by Weinreich et al. in their aptly named "Darwinian evolution can follow only very few mutational paths to fitter proteins"[1]. Many mutation combinations don't have additive effects on every aspect governing protein fitness (expression, stability, function, etc.), and

Conformational entropy could still matter in miniprotein binder design

Antibody V-regions improve their affinity for targets by both creating more high-energy interactions and reducing the conformational entropy of their antigen-binding loops[1][2]. Entropy's importance in antibody-antigen affinity seems obvious, given that loop residues largely mediate binding[3][4]. But for de novo-designed miniprotein binders, which often

Glutamate- and lysine-rich designs are susceptible to expression failure resulting from adenosine-rich sequences

High rates of glutamate and lysine introduction are a staple of structure-based sequence design by ProteinMPNN and related models, regardless of who trains them[1]. Recently, an analysis of the Bits in Bio competition showed that high glutamate/lysine content is predictive of expression failure[2]: The authors traced this

Essential proteins are more thermostable and over-expressed than non-essential proteins

Several properties of proteins have a sigmoid-like effect on cellular fitness. Thermostability is one of them: beyond a certain threshold, increases in protein thermostability confer no benefit, and decreases impose no penalty[1]: This concept, termed the principle of marginal stability[2], is somewhat contradicted by the observation that essential
