Over three decades, Peer pioneered protein domain discovery (WW, HEAT, BRCT), built foundational resources including SMART, STRING, eggNOG, and iTOL, and transformed microbiome science with the 2011 discovery of human gut enterotypes, cited nearly 10,000 times.

Validation raised the executable analysis intent fulfillment rate from 0.061 to 0.378, with parallel execution achieving up to a 29.9-fold speedup over sequential runs.

On a 500K-genome dataset it cut wall-clock time from 12.1 to 2.3 hours against the state-of-the-art PCAone, a 5.26x speedup, while preserving near-identical PC accuracy.

Iron proved essential for growth, with complete deprivation abolishing it entirely, supporting a proposed hemolysin–iron–ROS–Hippo pathway potentially relevant to colorectal cancer progression.

Across varying agonist:antagonist ratios, even a single IPC molecule among four bound ligands was enough to re-close an open pore, and pore widening occurred asymmetrically along the S7b helix gate rather than through uniform radial expansion
