What's a GeneRIF?
  1. characterized the folding pathways of the Escherichia coli rhomboid protease GlpG and the human beta2-adrenergic receptor. Despite their evolutionary distance, both proteins fold in a strict N-to-C-terminal fashion, accruing structures in units of helical hairpins

  2. we present a detailed protocol for optimization of expression and purification of three rhomboid proteases from Escherichia coli (ecGlpG), Haemophilus influenzae (hiGlpG), and Providencia stuartii (AarA).

  4. Unbinding of TM5 from the rest of the structure exposes GlpG's active site, consistent with studies of the catalytic mechanism of GlpG that suggest that TM5 serves as a substrate gate to the active site.
