====== Projects 1136-1139 ====== {{:ru:l9.jpg|}} [[http://www.rcsb.org/pdb/explore/explore.do?&pdbId=1CQU|1CQU]] Similarly to projects 1130-1133, these 4 projects explore the fleeting yet critical transition state region for transitions present for L939, the 39 residue fragment from the N terminal domain of ribosomal protein L9. To identify these structures as true transition states structures we must observe that half fold and half unfold. Unlike projects 1130-1133, here we study the barrier crossing at room temperature.
